That would be nice indeedI have a A800 I been using for the last few months before I review it on my YouTube channel IowAudio Review. After I do my video I could send it in so we can find out if its really any good.

I hope this amp doesn't test out as absolute junk cause I do like it a lot. Not sure who I need to be in contact with to get this thing sent in and scrutinized.
Thanks, sounds goodI've been using it as my main power amp to drive my home stereo setup. I run spdif/optical from my PC to a Emotiva PT-100 DAC/Preamp and that feeds signal to the A800 via RCA. So far in my use case its dead quiet when not playing music and even when playing high quality audio files. I have the gain on the A800 set just a click or two under max and use the PT-100 to control overall volume. Typical preamp/amp relation. I've left it on for days by accident to find it only barely warm and after hours of near clipping rocking out with a case of beer and Rush 2112 it gets good and warm but never actually hot. I had a Sony V333ES I loved dearly before this but it was big, hot, and heavy. For me the A800 beats it in every way and has convinced me of Class D's potential. Possibly even getting a second and running 2 of them in mono so I have 800w x 2. Not cause I need it but having lots of head room should allow the amps to stay more composed. If you watch my sound demo on the DCM bookshelfs or the Sony CS5 put on some headphones to get a vague taste of the A800. https://www.youtube.com/channel/UCpT_kN60jHU2YBhpiyW0ChA

Genuine question. Can someone explain how the A800 can output 800W from only 60W of mains power if class D is said to be ~90% efficient?
Internal Capacitors for momentary power bursts, not seen at the mains (60w in this case) input side. Like a 2,400W mains input charging up an electric car that is rated at 200KW (200,000W). Also I believe that mains input rating is an average likely use case not maximum possible, as the appliance (amp in this case) is not a fully resistive load like a heater. Could be wrong.Genuine question. Can someone explain how the A800 can output 800W from only 60W of mains power if class D is said to be ~90% efficient?
