I just found a used PS Audio GCHA for sale, so it is time for this to go to another good home.
I am the second owner; original owner kept it purely stock.
I replaced both the input and output capacitors with audiophile-grade ones of higher quality (note the expensive Hovland Musicaps on the input).
I also will include both the OEM power supply(unregulated) and much better Elpac(regulated) supply.
I installed an op amp socket, so that you can roll op amps if you wish.
I will ship it with its current op amps, dual BB OPA627s(some of the absolute finest available).
I have put about 100 hours on this unit since I bought it. Works and sounds fantastic.
The upgrade costs nearly the same as the amp when new. I am asking $150 shipped CONUS + PP fees. Manual will be included also.
