Wow. Unreal how much you have been able to cram into those enclosures. Are you happy with the result? I.e. how does it sound?

Oh my! That is a true "muscle" DAC. Incredible power supply unit!
I am sure that its sound is of the same level.
Unbelievable implementation nedi. All respects to you.

Regarding the sound of my amplifiers... is a true vintage sound. With simple words, it is like the sound of a Chevy Camaro V8 or a Lamborghini V12 compared to the sound of a... turbo sport Nissan or Mitsubishi .
BTW i have a... crazy idea: to build a SET with... four 300B's in... V4 arrangement. I will need a 1.2KVA power transformer to feed the tubes and a... special M6 core/400W output transformer. So i will get: 4X10W= 40Wrms of pure single ended, no feedback, true class A vintage sound .
Yeah... that would be a real "muscle" tube amplifier. Like the old muscle American cars.
For me it is only single end amps. Also I understand, from better designers than I, that parallel tubes even in SE, are not a good way to go. Nothing beats Class A SE amps for absolute purity of tone especially in the mids. Just rely on efficient speakers to provide the volume.

Without a doubt this one is running for "largest DAC ever"...

Care to decipher what is inside and for what reason...? I spotted two C3G's hidden between all the other parts.

You have inspired me to have a go at an amp something like yours. I just purchased two pairs of 171-A 1920s "balloon" triodes. I would like to house them in something like what you have built. My wood work is not the best and I don't know anyone who could build the case for me. So in the end the amp may be simpler just with unusual low power tubes.
