Very nice build my Greek friend. Very very professional...

Does this mean you will stop with your"hardcore DIY-Home etched PCBs- with lots of Solder over tracks-with a cluttered bench in the background", that we are accustomed to see all over DIYA?
It should almost feel like the best and ultimate builds for yourself... Sure looks like it to me.

All stuff melted together, up and running. Stereo amp + log VU meter + headphone module + input selector + ak4490 DAC + tube PSU + soft start + DC blocker + 30% free space in enclosure.

Couldn't resist and made quick 4L box for PS95 - small speaker with big sound.

Regards

Nice!
I like the DAC integrated in an amplifier.
What is the controller?

Input selector controller is simple 4 position rotary switch (but can be raplaced with some remote controll too).
Nice dual mono setup there, Plenty work with enclosure, like it a lot.
