Parasound HCA-806 6ch Amp Clean & Powerful

This amp is in great condition and has lots of power for HT or 2ch stereo. I just had this amp checked & cleaned & bias set for $120 and it sounds fantastic! Upgrading to to higher end 2ch amp and no need for 6ch. This amp can be bridged to 2ch for a very clean & powerful sound. This is a real classic from Richard and John Curl. Feel free to ask any questions & Thank you!
