This is a one-of-a-kind, excellent condition PS Audio GCC-100 integrated amp modified by the PS Audio "factory" (Rick Cullen of Cullen Circuits who designed/built some of the PS Audio's products). Dual mono design with "Gain Cell" input stage and a pair of the ICEPower 250ASP modules which were regarded to have the best sounding top end of the GCC/GCA amps if you can get by with 100watts/8ohms (I was pointed in that direction by both PS Audio and Rick Cullen).  Some reviews:

Cullen Level II Signature mods take this great performer to another level and included:

• Stock gain cells replaced with higher-spec custom gain cells
• All signal wiring replaced with Kimber multi-strand OFC (input and speaker)
• ERS cloth applied in key areas
• WBT NextGen 710 speaker binding posts
• ICEPower modules modded with Dale RN-55 copper leads and Muse audio caps

Amp new cost $2800 plus about $1000 for the modifications.  I am the one and only owner and have the manual and original double boxes for shipping.  It has been very well cared for in a smoke-free home.  Amp is in perfect condition... I can't see a scratch or blemish anywhere, though the remote does show some edge wear.  Asking $1450 with PayPal and conus shipping included.***SOLD***









Custom gain cells with ERS cloth applied can be seen at the top of the following picture:


Wiring between input board and amp modules replaced with Kimber OFC, mods to amp modules can also be seen in this shot as well as the new speaker wiring:

I use a Cullen modded GCC-500 and I can say these modded GCCs are GREAT sounding amps- head and shoulders above the stock units.  The GCCs can drive any speakers, too, down to 1.5 ohms. If I didn't own mine, I'd buy this in a heartbeat. You'll need big $ to beat this, IMO.

I also have a Cullen modified GCC-100, exactly like this one. It's terrific. The stock unit was once Stereophile Class A. As the OP said, the modified version is a few levels higher sonically than the stock. Add it all up, and you have one superb sounding, extremely well-built, and reliable amp.
