Anyone ever heard of it? 1990/91, build quality seems insane. There is a local hifi that had it used for sale but it quickly went.

AudiogoN ForSale: Sony CDP-X777es

I owned the X707ES briefly and thought they sounded great but I still prefer the sound of the newer XA7ES, and SCD-1 to it. I would suggest you not to buy it as the laser units for older Sony CDPs are discontinued.

It's a good red book CD player. I had one of these for few days in my system several years back. If the laser assembly brakes you are done, unless you have a way to get a replacement. I really liked this Sony as a transport, much more than a CDP.

True. Most buyers use these older units as the transport. Most older highend Sony CDP share the same transport as Accuphase units and Sony "R" series units.

This player uses a KSS-281A laser unit, which seems to be about as obtainable as a Philips CDM-9 Pro, etc. As in, not.
