For sale is one used QCS PLX1602. I am the original owner of this amp and it has never been pushed. I used it bridged for the first 6 months I owned it but never pushed it then either. For the last year I have only been using the left channel but the right channel works just fine too. This amp has two scratches on the top of it from being rack mounted with other gear (Eden Navigator). The amp has always been rackmounted. The front and back are flawless. More information on this amp can be found at http://www.qscaudio.com/products/amps/plx/plx.htm I am asking for $425 OBO shipping included via UPS in the US only. I will accept PayPal. Please PM me with questions you may have.
