My work mate built an amp, he has been working on audio products all his life and now it's a hobby. I am going to start learning electronics and hopefully start building my own some day.
The two green guys are like reverse engineered gain blocks turned into an opamp of sorts which is connected by 6 large gold pins to the main PCB. The design come out of an exercise to build the ultimate low noise low distortion gain block and subject of a research paper presented at an Audio Engineering Society. The sound is pretty amazing and I was A-B'ing with a Burson Lycan with two V6 singles and this amp shown here in the picture was vastly superior in terms of dynamics, tonality and had a very black background with little to no noise.
I should have an enclosure for it soon and might get a Khadas tone board to go along with it and will update once it's complete. I just thought I's share his handy work as it was very unique and is almost as good or equal to a THX 788 I recently had but would have to A-B it's that close. My source was an AK4490 DAC from an xDuoo TA-10.
In terms of power he had seen the specs for an NFB.11 and said power is pretty close to that so that is well over 2 watts @ 32 ohms. It's also powered by a NOS 20w US Robotics power supply. It is very simple looking overall but there is a lot going on with those two green guys. I was also running a pretty much stock T50RP with ZMF pads and it sounded great, EMU Teak was pretty amazing on it too.
