Maybe we can improve the nobrainer amp with something like this even further :Class-B output stage with feedforward.

As I posted before, I am really pleased with the outcome. IMO the most important modd was reducing miller cap. This way freq response became much more linear and extended in the highs.

Although it sports low gain, it can confortably be used with a 1:1 preamp with my sensitive 4ohm speakers.

Very low noise it conveys an agreeable soundstage free of fatigue inducing gremlins.
Bass is somehow less well controlled in comparison with my modded 103 and the highs are also less extended so the stage is not so large but I can not point any big flaws. Quite good for a very low power amp with such simple but genial schematic.

I am preparing myself to move to a bigger house and I will use it in my lab as bench amp.
Now I need to build some dedicated speakers.

I think he wrote DCB1 which is the DC coupled version with Salas shunt regs. A different animal that sounds better than the original B1. Not many buffers sound so well with only 2 JFETs per channel. As I have one myself I compared it to quite some preamps and till now no opamp based preamp was a match for it.

But you are are right in a way, there is life beyond any electronic device.
