Here's the inside. It's clearly a Cmoy done right. It still uses a voltage splitter but a more than basic one. Still means the supply impedance is a bit high and not extremely stiff. I do think this is just as good as 3 channel amps unless you need a lot of current and he may have done a bit more here besides to help with current load. This looks to have electrolytic output coupling caps which can be fine with some tayloring which it looks like he does. They are however not upgraded type electrolytics. That may not be needed with when bypassing. The first thing I did with a recent build I'm doing for review was bypass (parallel to) the output caps. It appears that he's doing the same and may also be doing so on the PS. It's basically pretweaked. I wonder if there's a resister in series to the output. The 8610 doesn't need it but that may not be so for all his options. The diode is likely a zener to protect from overcharging and/or as a simple V regulator for the wall wart. This device is about a smart guy that knows how to build and voice something but isn't ground breaking in any way. That is actually a compliment but at the same time, it can't be a 'best there is' type product, especially when offering voicing options. It can however be a VG sounding amp with a slightly warmer/rounder than real bass into certain loads.
