Vinnie,
This is one of the units that started the chip amplifier buzz a little over a year ago on these forums. This Sony unit is an all in one box, featuring all the goodies of HT, with quality two channel playback with a decent transport that supports a great SACD section. This unit has recieved constant play for well over a year doing duty on my parents Polk LSI system. They purchased a new receiver due to remote control problems with the Sony... and I hooked it up to my main system for the first time in well over a year - and WOW!! I recall it being good, but not to this level.
I've gone through the JVC, currently own the TEAC, been through the little $15 battery powered wonder, Griffin Power Wave... and I must say this unit holds something very special. I can tell there is still a lot of potential being held back.
I guess what Im trying to say is - is there any chance you would take this unit under your skillfull scope and see what can be done?
Im sure chasis damping would help, along with tightening around the fan as it makes fairly loud noise while running *but can be remedied by pressure being applied around the fan*. Beyond that, I have no idea. I just know that this unit has massive potential that has yet to be fully realized.
Your plate is full so I certainly do not expect an answer anytime soon. Just the same, I would love to see what is possible.
Thanks
Sean
