My new hybrid amplifier

Yesterday I made some simulation with NJW0281/0302 as drivers, and the result looks promising as well.

I thinking about the bridged solution. I can't really find the reason why it sounds better. It's doubling the number of the devices in the signal path, so it should be worse...

Now I have the schematic of the Pioneer A9 power amplifier. There are some difference, as I compare with Marantz, but I'm sure, that same engineer/team designed both of them!! This is real surprise...
