This is an updated page of my original Sony TA-E9000ES page that was hosted with Omen Internet.  The Omen site recorded in excess of 25,000 hits since it first went on-line on the 13th June, 1999 until the server monitoring the hits was de-commissioned and subsiquently the server hosting the page.  Thank you to all who e-mailed me with your comments, suggestions and questions.  I hope the information contained in that page and its links proved helpful to fellow Sony TA-E9000ES owners.  Now it is time to move on and update the page and add new links now that the information has a new home.

The Hardware

First Impressions

The Sony TA-E9000ES pre-amplifier is a heavyweight.  Tipping the scales at 12.8 kilograms (28 lbs, 4 oz.) it is no flyweight in the AV control pre-amplifier stakes.  Physical dimensions are 430mm wide x 150mm high x 387mm deep (17 x 6 x 15.25 inches) which places it in the typical format for today's full sized hi-fi components.   The weight of this unit belies the modest power consumption figure of 72 watts quoted by Sony.  As most audiophiles would agree, power supply is everything in an amplifier - especially in the power amplifier stakes, but in a pre-amp?  So what is the story with this pre-amplifier?   I would suspect that Sony had not only thought about good power supply regulation, filtering and separation of the supplies for the analogue and digital circuits but also reliability.  What most people perhaps forget is that digital circuits consume power even if they are not passing or processing signals.  In fact the current consumption is almost constant, thereby requiring a power supply capable of delivering this sustained load over the lifetime of the device.

On unpacking this unit and installing it amongst my other hi-fi and home theatre components one can't help but admire Sony's commitment to build quality and superb standard of finish for the majority of their ES products.  For starters, the exterior case of the TA-E9000ES is constructed of a heavy gauge steel and is well ventilated on both the top and side panels.  Not one of those ultra thin sissy jobs that one finds all too frequently on cheaper units.  The front panel is a brushed aluminium finish in Sony's new colour (for European, Australasian and Asian models) being a light shade of silver / champagne gold.  Fortunately not that deep gold hideous finish that Marantz became so famous for, or dare I say infamous for !  The front panel has a fairly austere (British / European) look and lacks many of the knobs and buttons that seem to decorate most AV equipment that one normally associates with the Asian / Japanese electronics.  Instead Sony have opted for only three small knobs to control input selection,  menu selection and parameter adjustment in addition to the usual volume control as a larger control on the right side of the front panel.   Eight very small "button" switches control other functions and adjustments, whilst the large rectangular switch on the top left corner turns the power off and on to the amplifier.  A stereo 6.5mm headphone socket is provided for the obvious.

An infrared receiver window and a separate transmitter window are located on the front panel.  The receiver is just above the headphone jack and the transmitter below the volume control on the right.  The front panel sports the Dolby Digital, DTS, MPEG Multi-channel and Sony's Digital Cinema Sound logos which gives even the casual glancer a quick insight into what goes on in the electronics behind the facade.  A generously sized plasma display gives clear visual indications to the user of the status of input selection, decoding system employed, playback channel indicators, surround mode and additional information about the source signal format that is too involved to expand on at this point of the review.  (More about the display later).  A row of eleven small orange LEDs (Light Emitting Diodes) above the main display illuminate to indicate the selected input and a row of five similar indicators are located below the main display window to indicate menu selection.

The rear panel is a very well and logically laid out collection of connectors for the interconnection of almost all sorts of AV equipment one is likely to want to interface with the TA-E9000ES.  Personally I would have liked to see a few more inputs (both analogue and digital).  I have a few pieces of equipment that would have benefited from the presence of more interfaces that haven't been fully satisfied by this unit.   All wire connectors have been gold plated to keep resistance low and reduce the possibility of noise at interconnection points due to oxidation.  A single switched AC mains outlet is provided on the European and Australian models and the US version has two.  My only criticism of the unit I have is that the AC mains outlet is a European round two pin without an earth.   This doesn't follow Sony's previous standard of  two pin IEC AC mains sockets.  In my case, this means my existing remote controller /  high power AC mains switch unit will not function with the new Sony unit until the mains socket is changed to suit the pre-amplifier.

Documentation

The Sony TA-E9000ES AV Control pre-amplifier comes with a very comprehensive and informative user manual.  Published in several languages it guides the user through the initial setting up, familiarisation with controls, tips on enjoying surround sound, adjustments of the speaker setups, equaliser, surround, level and customising features amongst many other topics.  The English language version of the manual is covered in 49 pages which include many detailed and comprehensive diagrams to assist even the most novice of users in obtaining a satisfactory result.  I would however advise that you sit back with a cup of coffee or two and take time to read through the user instructions a couple of times before making any component connections to the unit and attempting the "SETUP" procedure.  By following Sony's suggestions regarding interconnection with other components you should not experience any difficulty in getting the E9000ES up and running within a short time.  In my situation I decided to re-arrange the physical location of my existing components so the process of interconnecting all the devices took a little longer than expected.  With so many connections to make I decided to completely strip down all the interconnecting cables, make a thorough visual inspection on their condition and sort them into lead type and length.  Having discarded any leads which had seen better days I gave preference to those which were of high quality had gold plated connectors.  As the Sony has all its audio and video connectors plated with gold it seemed to make sense to avoid the potential problems of dissimilar metals by not using the nickel plated leads.  Besides nickel plated connectors are reputed to have a sonic signature of undesirable characteristics, so they are best avoided in a high quality installation.
 

Power Amplifier Hookups

Sony provides three dual RCA (phono) to RCA leads for the interconnection of the E9000ES to a suitable five channel power amplifier.   The supplied leads allow the user to physically separate the red and white leads to allow for independent connection to an independent sub woofer amplifier.   I opted not to use the supplied leads as they were not long enough to reach the location of the power amplifier.  Instead I used low capacitance double shielded cables from another manufacturer to establish the audio link between the TA-E9000ES and the matching Sony TA-N9000ES five channel power amplifier.  Using the supplied CONTROL A1 cable that came with the power amplifier allows the Sony TA-N9000ES to be switched on and off via the pre-amplifier.  The only negative criticism I have of this arrangement is the Sony TA-N9000ES has a "warm up" mode that can't be activated from the TA-E9000ES pre-amplifier or via the supplied remote commander.  This effectively means cold starts only in this configuration.
 

Digital Component Hookups

The TA-E9000ES has a wealth of digital interconnection possibilities with other components.  The upper level of the back panel has no less than five optical inputs (CD, MD/DAT, DVD, TV and LD), and a single optical output (MD/DAT) all via TOS Link connectors.  Other digital inputs are via three RCA coaxial sockets for CD, DVD and LD for bitstream sources and one AC-3 RF connection for LaserDisc.   In my opinion just enough for the average user.  In my case not enough, and I would have preferred Sony to have included at least one other digital input (perhaps a coaxial connection for the MD/DAT input), and at least one additional digital output or either coaxial or TOS Link optical format.  The reason I have suggested this is that my digital recording / replay components consist of both a Sony MDS JA3ES Minidisc recorder and a Philips DCC900 Digital Compact Cassette recorder deck.  I have doubled up the CD digital input capability of the E9000ES by using the TOS Link optical connection for replay from my Sony CD player and I am utilising the coaxial bitstream input for replaying tapes from the Philips DCC unit.  This arrangement still leaves me without an independent digital connection for recording on my DCC deck.  I'm sure I'm not the only person with this dilemma.
 

Analogue Audio Component Hookups

The E9000ES provides five sets of gold plated RCA connectors dedicated for the connection of analogue stereo audio sources as inputs.  These are for moving magnet phono cartridge, tuner, CD player, MD / DAT and tape.  The latter two having stereo analogue output sockets to interconnect with these components.  Analogue stereo inputs are also provided for connections to TV, DVD player, LaserDisc player and three VCRs.  The three VCR (Video 1, 2 and 3) interfaces also have stereo audio outputs as well.  As with the with the five audio source connections, these too are gold plated RCA connectors.
It should be noted that this pre-amplifier does not have 5.1 analogue bypass for connection of multichannel or stereo sources from external decoders or equipment such as Super Audio CD (SACD) or DVD-Audio (DVD-A) player which have their own proprietry digital decoders built in.  To acheive this using Sony ES components you will need to purchase the Sony TA-P9000ES multi-channel pre-amplifier that has two 5.1 inputs, one 5.1 bypass input and one 2 channel bypass mode
 

Pre-amplifier Outputs

Eight gold plated RCA connectors couple the analogue output signals from the pre-amplifier to the power amplifiers.  These are designated as Left and Right Front, Left and Right Rear, Center (2 connectors) and Woofer (2 connectors).
 

Video Interfaces

The Sony E9000ES supports both composite video and S-Video sources via gold plated RCA connectors and gold plated 4 pin mini-DIN connectors respectively.  All six video sources of TV, DVD, LD, Video 1, 2 and 3 accept signals into the AV control unit.  Composite and S-Video sockets provide video outputs to the three VCRs (Video 1, 2 and 3).  Two pairs of RCA and 4 pin mini-DIN connectors provide composite and S-Video outputs to the video monitor(s) or television.   The control unit also has both RCA and 4 pin mini-DIN connectors for input and output to an external video processor.  A nice and useful touch to the design features, worthy of mention.
 

Control Interfaces

Sony have allowed for control interconnection between the pre-amplifier and other Sony compatible components by incorporation of two Control A1 S-Link cable sockets on the rear panel.  These allow the control unit to sent signals to other Control A1 compatible products to switch things off and on amongst other functions.  A single Control S input is also featured which allows a Sony television with this supporting feature to cause the E9000ES to automatically turn on when the television is switched on.
 

RS-232C Connector

The E9000ES incorporates a 9 pin Sub-D connector on the rear panel.  This is provided to allow users (owners) and Sony service centres to provide upgrades to the software held in flash ROM within the control unit.  As the E9000ES has two SHARC 32 bit floating point DSP chips with enormous digital processing power the performance and functions of the DSP modes can be enhanced and upgraded via simple software changes.   Since the TA-E9000ES was orginally released, Sony has released several free software upgrades and two purchase upgrade kits.  More information about the software upgrades can be found here.  I'm pleased Sony has taken a sensible approach to a design feature that will potentially prevent this unit from becoming prematurely redundant.  A problem so often prevalent in these times of rapid technological change and development.
 

Analyzer

The mystery connector in the form of a 3.5mm socket appears on the top left corner of the rear panel of the E9000ES.  Designated simply with the label "ANALYZER" and "MIC IN" the user handbook explains this as for use with future upgrades.  One can only guess the purpose of this connector except to assume that with a good quality microphone connected to this port and under some possible software control the function, the function of the E9000 can be extended to spectral analysis of the listening room acoustics resulting in possible and subsiquent equalisation of these via the DSP circuitry.
 
 

Interconnection the TA-E9000ES with other components

Inteconnection the Sony with other hi-fi audio and video components is a breeze.  The handbook provided with the unit is very helpful in this respect with many clear diagrams to illustrate all manner of possibilities along with easy to read understandable text explanations.  Sony should get accolades for the effort in this respect.  Some seven pages of the user manual are devoted purely to this subject.  Nothing is left to the imagination and therefore mistakes are not likely to occur even with the most novice of users doing the work.

Three pairs of gold plated RCA to RCA leads are supplied with the unit for the purpose of interconnection with a five channel power amplifier and active sub woofer.  No Control A1 cords are provided as one is supplied with the Sony TA-N9000ES multi channel power amplifier and the Sony TA-P9000ES multi channel pre-amplifier.
For the remainder of analogue audio, video and digital signal connections, the user must supply these leads.
 
 

Description of the front panel controls

The front panel of the E9000ES is rather spartan when compared with many models offered by Sony's competitors for an AV product in this class.  Even other ES amplifiers seem to have a miriad of controls in comparision, albeit that they might be concealed behind a flip down panel.  Instead of decorating the unit with dozens of knobs, switches, buttons and flashing lights; Sony has opted for the minimalist approach with the E9000ES.  However don't let this lure you into a false impression on the audio and video capabilites or features of this machine, for below that subtle exterior beats a heart of a pure digital processing powerhouse.

A rectangular POWER ON/OFF button provides power activation / isolation for the unit.  To switch the unit from STANDBY to ON a simple touch of the appropriate input on the touch screen of the supplied remote control is all that is needed.  Likewise switching the unit from ON to STANDBY requires the toch of a button on the remote control.  A small red LED is illuminated when the unit is in the standby mode and goes out upon activation of the unit.  Next to, and just to the right of the power switch is a small button designated "MAIN MENU", which, when depressed momentarily is backlit by an orange glow.  Each depression of the button steps the E9000ES through the various menu options of << SP SETUP >> (speaker setup); << EQUALIZER >> ;
<< SURROUND >> ;  << LEVEL >> and  << CUSTOMIZE >>.   These selections are echoed by the illumination of a small orange LED linked to the function selection below the main plasma display in the centre of the front panel.   The "MENU" rotary control  allows selection of the desired parameter from the current menu selection.   Adjacent to this control knob is the "+/-" control that can be used to adjust the setting of the currently selected parameter.

Source input selection is acheived by rotation of the "INPUT SELECTOR" rotary control.  A row of orange LEDs above the central display illuminate corresponding to the selected source.  A small button above this control allows the user to select between auto, analogue, optical, co-axial or AC-3 RF signal source depending on the capability of the selected input.

Below the main display is a row of button switches designated "EQUALIZER BANK" which allows the user to select from no equalisation (flat frequency response contour) or to five other user defined settings; "AUTO FORMAT" which automatically selects the source signal format and performs automatic decoding; "MODE - and +" which allows the user to select the appropriate soundfield; "2ch" which disables the surround modes and performs normal two channel stereo reproduction; and finally "AUDIO SPLIT" which allows reproduction of the audio from one source whilst viewing the video from another.
On the far right side of the unit is a large rotary control marked "MASTER VOLUME", the purpose of which I believe should not require explanation.
 
 

Specifications

Sony's aclaimed performance specifications for the TA-E9000ES are in line with what one would expect from an AV control unit in this class.  Low harmonic distortion of 0.05% with a respectable signal to noise ratio of 100dB for digital inputs, 82dB for the phono input and 94dB for the remaining analogue line inputs.  The line input figure signal to noise ratio is quoted with respect to an input level of 2.5 volts which is respectable but nothing exceptional.  All five channels have levels which are independantly adjustable, however equaliser settings are restricted to left and right front channels (as a pair), left and right rear channels (as a pair) and the centre channel independantly.  Control of the sub woofer (Low Frequency Effects) channel level is also provided for.

The Surround Fields

The E9000ES supports automatic decoding of multichannel digital audio sources from program material encoded as Dolby Digital AC-3, dts, MPEG and AAC* multichannel.  Recent software upgrades have added additional soundfields to the original package supplied by Sony.  Sony market two software upgrade kits which add additional decoding modes and soundfields.  The VUCD-E9000A kit (V2.01) adds MATRIX 6.1 decoding and six additional soundfields to the already impressive list as well as enhanced bass management features not available on earlier software versions.  (* AAC decoding is only available if the unit has been flashROM [ software] upgraded to V2.50)  Sony market an upgrade kit VUCD-E9000B (V2.50 software) which adds AAC decoding for Japan's domestic satellite television service.  Of course decoding of analogue multichannel source material like standard Dolby Pro-Logic is also supported, but sadly no Pro-Logic II at this stage.  Standard two channel stereo reproduction is also possible.

The AV control unit can simulate multichannel surround sound from conventional two channel stereo sources.  The Sony has both conventional modes that utilise the front and rear speakers as well as virtual modes that use only the front speakers to create the surround soundstage.  These modes and their use are very well explained in the user handbook supplied with the pre-amplifier.  In fact Sony have gone to considerable lengths to explain each mode and how to set up your system and speaker placement for optimum reproduction and enjoyment of surround sound.

One thing I liked about the set up of the E9000ES other than the very easy to follow instructions, was the ability to be very flexible with speaker placement and size.  In this regard Sony has catered for just about every possible installation.  The "Main Menu" "SET UP" function allows the user to select speaker size (large or small) for front, centre and rear independantly.  This allows low frequency bass signals to be corrrectly re-directed to the larger speakers or sub-woofer ensuring the soundfield and sound remains balanced.  The low frequency cut-off point can be set by the user, below which all bass frequencies will be re-directed to the large speakers or the sub-woofer as appropriate.

Placement of the rear speakers is very flexible, allowing them to be placed into three different locations with respect to the listening position as well as being placed on the floor or in elevated positions.   The only requirement on the user is to measure with some degree of accuracy the distances from the front, centre and rear speaker locations to the prime listening position for optimum surround sound reproduction.  The E9000ES "SET UP" menu lets the user set these distances to within 0.1 of a metre.   The adjustment range for placement of all speakers is from 1.0 to 12.0 metres or 3 to 40 feet.   This ensures the correct delay for the sound reaching the listener's ears.  Adjusting the distance by 1 foot is equal to changing the propogation delay time by approximately 1mS.

SEMI CINEMA STUDIO EX.B Creates a 3D soundfield imaging of V.MULTI DIMENSION of 5 sets of virtual speakers without actual rear speakers similar to Sony Pictures forefront-class acoustics facilities in Hollywood. Does not use rear speakers (V2.01 only)
SEMI CINEMA STUDIO EX.C Creates a 3D soundfield imaging of V.MULTI DIMENSION of 5 sets of virtual speakers without actual rear speakers similar to Sony Pictures for the BGM recording of movies. Does not use rear speakers (V2.01 only)
AUTO FORMAT DECODING Automatically detects the type of analogue or digital signal being fed into the pre-amplifier (Dolby Digital, MPEG, dts, AAC* and Linear PCM) and performs the proper decoding of the signal. Automatic detection of Pro-Logic encoded signals is not possible.
AAC decoding only possible with V2.50 software installed.
VIRTUAL MOVIE PHONES Simulates virtual surround sound through normal stereo headphones. Only available when headphones are plugged into the headphone jack on the front of the E9000ES.  This mode is not selectable from the front panel of the unit or the remote commander.

Using the Sound Fields

The sound fields can be selected from either the main unit or via the Remote Commander.  Selection of the CINEMA STUDIO EX, MATRIX 6.1 and SEMI C. STUDIO EX modes can only be made if the unit has been flashROM upgraded to V2.01 software.  In most modes the effect level, wall type reverberation time, low frequency effect mix, dymanic range compression, front balance, rear balance, rear level, centre level and sub woofer level can be adjusted.  In some surround modes the effect level, wall type and reverberation time can't be adjusted.  Likewise in the surround modes of Small Hall, Large Hall, Opera House, Jazz Club, Disco / Club, Church, Live House, Arena, Stadium and Game the centre level can't be adjusted even though the handbook and Remote Commander would imply that you can.  In these modes the centre speaker is mute and any attempt to adjust the level has no effect.  This information is somewhat misleading to the newcomer to this unit as most think it is a fault.  I assure you it isn't, and I'm a little dissapointed that Sony have overlooked this most obvious mistake in both the user handbook and the intuitive interface.

A useful feature is the ability to "trim" adjust the dialogue level and the rear channels level for each soundfield over and above the levels that you have established during the set up proceedure.   This is important as the mix down on certain program material may not be to your liking, thereby allowing you to compensate for this without destroying or losing your original settings.  Likewise being able to select from any one of five user defined equaliser settings once again assists in overcoming tonal imbalances in recordings.

In the modes of CINEMA STUDIO EX.A, B & C as well as SEMI CINEMA STUDIO EX.A, B & C :-  VIRTUAL SPEAKERS can be turned on or off; SCREEN DEPTH can be adjusted to three levels and REAR ENHANCEMENT can be switched off or on.

In VIRTUAL MATRIX 6.1 mode :- 6.1 MATRIX can be switched off or on and SCREEN DEPTH can be adjusted to three levels.  In this mode the equalizer bank settings become inoperative.

For detailed operation and comment on these modes read the V2.01 review.

Adjusting the Levels of Each Channel in the Surround Modes

The user interface is very friendly in this respect on the Sony.   The user has the option to perform the adjustments on the actual pre-amplifier unit itself or via the two way communicating Remote Commander.   I prefer the later option as it allows the user to tailor the adjustment for their preferred listening position within the room very easily.   I must however emphasise that before performing any adjustments to the levels and balance it is virtually impossible to get an acceptable result unless you have initially accessed the "Main Menu"  < SET UP > program and made the nessecary adjustments for speaker configuration and size, cut-off frequencies, distance to the prime listening position etc.   Failure to set up these parameters correctly will result in an unsatifactory and confused or blurred soundstage.  Fortunately this < SET UP > proceedure needs only to be done once and will never be required to be re-adjusted unless you change the placement, size or number of speakers in the system.   I would suggest the use of a tape measure to get the distances correct.

As far as setting the levels is concerned, Sony have made this pretty easy with an inbuilt test tone generator that can be conveniently activated and all adjustment made via the Remote Commander.  If all your speakers are identical for all five channels then setting up the levels is extremely easy.  Activation of the ''Test Tone" mode causes a white noise signal to be injected into each channel in turn, stepping around the soundfield at approximately ten second intervals.   The user then simply adjusts the levels (shown in dB for centre and rear speakers) and balance between front left and right, balance between rear left and right.  Feedback of what is happening appears on both the LCD screen of the Remote Commander and the central display of the main unit.  It is also possible to hold the test signal onto a particular channel to allow the user adequate time to perform exact level adjustments then continue through the reamining channels.  I found this feature helpful when setting up my own system.  Unfortunately I don't have five identical speakers in my configuration.  KEF three way units are used for the front channels, Richter Acoustics Unicorn as the centre speaker and Richter Wizards service the rear channels.  These were a hangover from my previous system that I used in conjuction with my Sony TA-E1000ESD pre-amplifier of which the TA-E9000ES has replaced.

If all your speakers are identical they will be tonally balanced and be of equal efficiency in the conversion of electrical power into sound intensity.  Using the test tone facility with this configuration should yield a very satisfactory and balanced result.  However, if your situation is similar to mine then getting a very good balance is somewhat more complicated.   I tried using my ears alone to make subjective adjustments of the sound levels from each speaker.  This resulted in a satisfactory performance but I found myself constantly fiddling the adjustments in an attempt to get a better sound.  The solution was simple.  I purchased an inexpensive sound level meter from Tandy Electronics for under AUD$100.   Using the sound level meter and the Sony's test tone facility it was possible to get a very balanced soundfield in a matter of minutes.   The only task left was to tweek the equaliser adjustments for the centre and rear speakers to tonally match the main front KEF units.   Once again this is not overly complicated.  I decided to break this task into sections.  First match the Richter centre speaker as best as possible to the KEFs.  By adjusting the centre channel equalizer I was able to use my ears to closely match the "colour" of the white noise from these units.  A small amount of level adjustment with the aid of the sound level meter and then I repeated the process comparing the front KEF units with the rear Richter units.  Within about twenty minutes the whole set up was ready to undergo the critical listening test.
 
 

The TA-E9000ES Intuitive Interface

The central display on the TA-E9000ES reports to the user the status of the pre-amplifier with details of the surround mode selected, source (optical, co-axial, AC-3 RF); digital bitream (Dolby Digital, MPEG, dts, AAC*, decoding mode (Pro-Logic etc); activated speakers and dynamic range compression mode.

When digital sources are detected and processed, the display can be scrolled using the "+/-" control to reveal additional information about bitsteam format (AC-3, dts, MPEG, AAC* etc) as well as sampling rate, bitrate, emphasis and dialog level depending on the source.  The unit is smart enough to identify the signal source characteristics and report this to the user.  Typical displays might appear as below :-

When playing a dts encoded CD -
dts [3/2]   >>>  STREAM=dts(unformat)[3/2]    BITRATE=(OPEN)    FS=44kHz    CATEGORY=CD-DA(IEC60908)    EMPHASIS=OFF

When playing a typical dts DVD -
dts [3/2]   >>>  STREAM=dts(IEC61937)[3/2]   BITRATE=1536kbps   FS=48kHz   CATEGORY=DVD PRODUCT   EMPHASIS=OFF

When playing a typical Dolby Digital DVD -
DOLBY DIGITAL[3/2]    >>>  STREAM=AC-3(ATSC)[3/2]    BITRATE=448kbps    FS=48kHz    CATEGORY=DVD PRODUCT   EMPHASIS=OFF   DIALOGNORM=27

EMPHASIS=OFF

When the source is a digital stream from a Minidisc player -
LINEAR PCM [44kHz]   >>>   STREAM=PCM   20BITS   [44kHz]   BITRATE=1764kbps   FS=44kHz   CATEGORY=MINI DISC SYSTEM
EMPHASIS=OFF

When the source is a digital stream from a Digital Video Broadcast receiver -

EMPHASIS=OFF (MPEG 2 transmission)
DOLBY DIGITAL[3/2]    >>>  STREAM=AC-3(ATSC)[3/2]    BITRATE=448kbps    FS=48kHz    CATEGORY=BROADCAST   EMPHASIS=OFF   DIALOGNORM=31
(Dolby Digital 5.1 surround transmission)
 

Analogue inputs are sampled at a 48kHz rate and encoded internally without emphasis.
 
 

The Critical Listening Test

What you have all been waiting for......    Before continuing I must comment that the Sony TA-E9000ES pre-amplifier is a marvel of electronics.   The build quality is outstanding and the user interface both informative and flexible.   Once the user has set up the system correctly the listening enjoyment can commence.   To simplify the evalution of the subjective performance of this unit I have decided to split the review comments into sections, each detailing my impressions.  These are my findings with the unit loaded with V1.18c software.  For a review of my impressions of the TA-E9000ES loaded with V2.01 and V2.50 software go here.

Stereo Performance

Now I can almost hear the cries.   What is the point of buying a surround processor if you intend to listen to recorded material only in two channel stereo?  Well, some material does not lend itself well to artificial manipulation of the soundfield.  The engineer who recorded the material and produced the final two channel stereo mixdown had possibly something in mind at the time of how the sound was likely to be reproduced in the home on a stereo system.  I found that some live recordings did not reproduce well when the soundfield was manipulated electronically.  The ambience was already part of the recording so why try to double the effect?

I used several of my favourite Compact Discs to evaluate the two channel stereo performance of the Sony.  The sound was very transparent and the soundstaging had incredible depth.  Accurate placement of both the instruments and vocals was highly evident.  I would have expected nothing less from a unit in this price range.  The signal to noise ratio was excellent even with the volume control advanced well beyong the fifty percent mark.  With an absence of input signal and the volume control attenuation to minimum (0dB), the background thermal hiss was only slightly evident when one placed one's ear close to the speaker enclosure.

The performance through the phono input was less impressive.  The
