HCA-2 Power Amp
Manual and Original Box
This is a flawless one-owner power amp from PS Audio. It comes complete with its original box and manual. There is not a scratch on it and it operates with no issues. This model was introduced in 2001 at a retail price of $1695.
Class A Hybrid design blends a Class A analog input stage with a Class D output stage. So you get the clarity of a Class A amp without all the heat (and $$$). At 150 watts x 2, it will power most speakers with excellent results.
