Amir,
If you are burned out on DACs and headphone amplifiers, I’m happy to lend you my Nobsound NS 10P minature tube preamplifier. I have the original Chinese tubes and set of Russian replacements.

I’ve been a solid state guy for my entire audio career and wanted to try the “tube sound” everybody talks about. This lets me give it a shot for little money. I use it to turn my O2 amp into a hybrid. Subjectively, it does seem to add some euphonics. It has a gain of 1.5x or so, and given the design of the O2 you can overload the amp on high gain with maximum volume on the preamp.
Naturally it comes with zero instructions. I can’t figure out if the tone controls are supposed to be at 12:00 for a neutral position and attenuate or deattenuate as you go left or right. At least by ear that is the way they sound. Also no idea what the curves look like, so that also might give you something to measure with your new toy!
I looked it as a fun way to add tone controls to my headphone setup. I’d say 9 out of 10 times I don’t use it when I’m listening.
