Parasound HCA-2200II High-Current 2-Channel Amplifier

Selling my Parasound HCA-2200II in excellent condition cosmetically and functionally.
I am the 3rd owner.
The amp is all original and has not had any repairs to my knowledge.

You can search the web for reviews and find nothing but praise. They are considered one of the best used amps on the market for a great price.

HCA-2200II ULTRA HIGH CURRENT AMPLIFIER. Our premiere amplifier created by legendary designer John Curl has been called by Stereophile,"...a benchmark product against which other amplifiers can be measured."
