** SOLD **
For sale is a Parasound HCA-2205A 5-channel amplifier in very good condition. I purchased it from the original owner with the intention of replacing my Parasound 5125, but the 2205A is too large to fit. It has a perfect front face, but rated an 8/10 due to one thin scratch on the top near the letter "D". See this link for my Audiogon listing, and PM me for additional (higher resolution) photos.
