    When I bought this amp I intended to buy a receiver to use as a pre/pro. I ended up with a Marantz 8200 and am happy with the internal amps so I am selling the Parasound 855. The amp is new and has only been removed from the box to make sure all channels are in working order. I will also include the 12V DC trigger cable which is somewhat non-standard.
    $375 Parasound HCA-855a. Buyer to pay actual S&H
    Comes with full 10-year warranty.

    Hey Don, I recently got one of these amps from another
    fella here in the forum. It sound great with my NHT 2.5i,
    I got them bi-amped! Now I need to get that Pre-pro....
    I have been very happy with this amp so far. BUT at
    85 watts a channel this thing still weighs in at over
    40 pounds, it's no light weight! [​IMG]
