Can't say I really know anything about it, but all of the X7 series players are very nice. Enjoy!

This is the "holy grail" of vintage 18-bit ladder DAC CD players of this era.  Its better than any of the TDA1541 players and is the pinnacle of the "45-bit" players built by Sony.   The next model year Sony went with the Pulse DACs and never again went back to using this sort of chip set.   There are better sounding stock CD players, but none were better at the time (1988-9) in stock form... Sound is comparable to many of the progressive modern DAC chipsets and unlike any of the players from this vintage.


Expect a very smooth and polished sound with virtually no digital glare.  Op-amps are superb, build quality is as good as it gets.  You have a keeper my friend!  And its all built around what I consider the best sounding DAC of all time, the BB PCM58.  My modder says there is nothing to do to this player... in fact its a typical case of Sony's "over-engineering".   Many of the tweaks Sony used really weren't necessary.  It was more of a statement piece than a practical application and very few were sold at its $1500 price tag when new.  


However, if you want to experience a "vintage" and more open sound, the lesser 508ESD/608ESD's which utilize the same exact DAC are much more entertaining.   You'll swear your listening to vinyl.   These players can be unleashed like Tim Tebow against the Steelers in OT when modded properly.   Ultimately one of these players would wind up sounding better than a stock X7ESD.


If you ever wish to "donate" it to me for evaluation purposes I'll always be receptive to the offer.   I have heard one side-by-side against a stock 508ESD, modded 508ESD, S9000ES, and SACDmods NC555ES.  It had a character all its own and a sound that was a glimpse into what would happen 10-15 years after it was first sold.   If I could find a mint one for a reasonable price I would most certainly own one.  


I would make the bold statement of saying that this was the best CD player Sony has ever released in stock form until the S7000/7700 and S9000ES came out.  The sound is very comparable to these units which were released over 10 years later!

Wow Scott!!! That's alot to take in & much appreciated...take a breath my friend :-)

I love the sound of this player..very smooth with more pronounced bass than any of my other players, but very contolled. The trebs are very sweet & crystal clear. I also noticed that i'm trimming back the volume of the STR-GX10ES a tad when i use this player....it has lots of go! Its such a nice piece that i usually reserve its playing time for when i can really relax & enjoy, while giving it the attention it deserves.

The X7ESD is rated at 40Ibs & the GX10ES is rated at 41Ibs, but the X7ESD is by far the heaviest of the two & quite noticeable at that!!! There's sections were the copper is "TRIPLE" layered!!! Even comes with figerglass epoxy circuit boards for high rigidity. Multiple stage power supply with Two independent transformers. What a beast!!! Definite keeper!!!

Besides Scott's great evaluation of the X7ESD, here's a good info link to the X7ESD

Its weight was an attempt to keep the platter as stable as possible, not really necessary, but it does help with resonant tuning, especially with less than perfect rack systems.

Enjoy this player while you can before CDs go the way of the DoDo.

If you like the sound of the X7ESD and want something to use everyday go with the S7000/7700 or S9000ES. All sound very similar, but for a fraction of the cost. I'd be anxious to hear what you think of the sound of those in comparison to the X7ESD.

Really?  Better than the XA7ES?  

What op amps does it use?

Given that I am not fond of the later Pulse DACs, I might not be the best person to give an objective opinion of the XA7ES. As a transport, the XA7ES most certainly has a sturdier mechanism.

From my understanding the X7ESD uses the NE5532 op amps. There are better alternatives available since its production,. I am not a modder, so I would rather not comment on what would work better.
