This was something of a “budget” amp from AudioAccess (a subsidiary company of high end manufacturer Madrigal Audio Labs). With 40W per channel into 12 channels and 80W when it is being used as a bridged 6 channel amp, the PX-612 was a fairly robust amp. Sound quality is really good (especially now for under $200!) and each channel has its own discrete transistor driver and output stages for greater reliability. The speaker outputs reside in a separate terminal plate which you can mount 4′ away and have the speaker wires terminate directly on to it. This proved to be very beneficial when you are running multi-zone speaker setups and don’t need to pull the amp out every time you want to check which output is for which zone.
Cosmetically, the amp looks good. Minor scuff marks here and there and a few hairline scratches but nothing major. We do not have the original box but will securely pack it for safe shipping. This is a quality amp Made In USA!
