Testing Chinese tube preamp all modded

Recapped and replaced all resistors in this little Chinese tube preamp with boutique caps, Mundorf Pio for output caps, coupling and interstage caps are Russian pio(K40Y-9).
Used a K75-10 (very large) as bypass cap for first section electrolytic bypass cap.
Will use some Mundorf PIO for other 2 sections.
Panasonic electrolytics,
Kiwame, PRP, TKD, Takman, Dale, Ohmite resistors.
Baldwin green label 12AX7 x2
1x rca black plate 12AX7
Military JAN 6X5GT/G tube rectifier.

Teflon bypass caps to follow… for output and Coupling/decoupling/ interstate Russian Pios.

Cornell Dublier and Kemet MKP caps for PSU bypass.
Also will add Alps Blue Velvet remote volume control.

Streaming Amazon Music HD… SMSL Dac @ 384k/32bit.
So far sounds amazing.. Going to my Prima Luna dialogue 7 tube mono blocks and the Martin Logan Aerius I electrostatic Speakers..
super dynamics and sweet mids…

Nice bass but a little muddy.. hoping the Teflons bypass caps will help with this.

I read the Russian Pio take 100hrs at least to burn in and start sounding optimal. So it will be a while…

Will test soon with Tube Phono and turntable… vinyl and tubes ! all analog signal path..!
