This is a pretty good amp! I'm pretty impressed. Relatively closely related to my tube amp in sound, only a bit more crisp with a touch less sweetness. Three-dimensionality is airy and really good. All in all nice and neutral with a nice musical flow. The reminiscence to the Nelson Pass concept seems to be really successful!
To be noted: I've increased the capacity of the power supply about 2.5 times for better stability. This with smaller capacitors to shorten the charging time. I also approximately doubled the heatsink area. I bypassed the Ero MKT capacitors at the input with small micas, which is a nice little mod for improved detail.
Conclusion: This thing is fun!
