I have some ECX10N20's around here somewhere and most of the parts and boards for the MoFo. But I don't think I want to sweeten things up anymore than what I have now, it seems just about right. With my previous SissySIT R.3, I always used a gain stage in front, either internal or external, to get the overall gain where I needed it for my system. And those gain stages were always "clean" to maintain that sweetness in the.... sweet spot..since the SS R.3 has it's own pleasing character. I listen to a wide variety of music and if the total distortion gets too high, I think things just start sounding too sloppy, particularly on complex material.
I really like this square law HGF. It just thrives into the lower impedance loads and sounds great. My speakers are essentially 5 ohms and not super efficient, so the amp has some nice synergy there..

Breaking the “no building in the Spring or Summer” over here.
I want to say it’s an entry level DAC/streamer, but I cannot tell when I listen to it. My Lord, what a rabbit hole!

Looks fantastic! Don’t tease us with those pics… tell us more. Which DAC is it? I recently ordered an R2R dac as well, though it hasn’t arrived yet.
@william2001 I totally get what you are saying with too much H2. I don’t need a lot of power, so the single ended follower is just right for me. But a push-pull lateral follower would cancel most of the H2. Now that would be interesting. Of course, there are tons of amps with that config already. Would be fun to try that with SCG driving.
It's a ProtoDAC. TD1837 X 8. A NOS DAC HAT on top of a Raspberry Pi 5.
In its current incarnation, the PSU is shared between the Pi and the DAC, which is not the best scenario. But it sounds pretty great already, probably because the Pi only has 1 job: Running the RAAT bridge.
At some point in the future, I'll add a low noise linear supply for the HAT, but for now, I just need to clean up the build and put a lid on it.
