HE-400, RE-400... Love them both! Greetings from Poland! :)

For output stage I am suing 2xSuperTeddyRegs +/-15V, all is powered from 30VA toroid and rectified through shotky bridges and CRCRC (3x2200uF, 2x5R) filter/capacitor banks. Also one 0.47uF each rail. If you're planing to power output stage and DSD1792 (5V) than you don't need to cut the...

It won't damage circuit, but if your amplifier (pre/integrated) has low input impedance you will get very audible distortions in the low frequencies, or you may even lost your bass sound at all.

carlmart   I've send schematic to your e-mail. It would be nice if you can clean it up a little bie (element positioniong etc.) as I have no time to do this.

Hi, I am using Two SuperTeddyRegs for power up analog stage. You can find schematic of STR on Teddy Pardo's website. In my case they are feed from separate transformer. Dc-DC converter is not used any more. The improvement was much bigger then all other capacitor changes, opamp swaping and and...

Hi, could you repost schmetics? The picture links from the first posts are gone. Thank you.

Try OPA627BP in second stage (you need browndog adapter), and maybe LME49740 on first one. I am actually running 2xOPA1612 on first stage and LME49860 on second, but I am aiming to neutral and transparent sound. Analog stage in my V-DAC is powered by two independent SuperTeddyRegs at +/-17V. It...

Hi I did some reverse engineering and have full schematic of this DAC. But without most of the values, as I did not need them. Schematic is little bit messy as I did not clean it up but again it was not necessary for my needs. I was just redesigning output stage (not only changing op-amps, but...
