As you can see from eLyric PS Audio controller, volume control slider acts nicely. I2S connection to DAC avoids jitter from S/PDIF receiver/transmitter and master clock is employed to reduce jitter even more.

Hi Marc,
I followed attentively the two first treads of Lazy Cat for a lot of time, and now I found this one.
The very simple amp I see seducts me, and so for your personal approche of it too. I already saw your works in an another french forum (GC, Zenquito, ...) some time before, which are impressives, chapeau bas.
If you agree, I would like you share your last Eagle stuff with 2SK1058/SJ162 (TO247).
Thank you in advance.
Michel

Hi all

As promised here are some pics of the first lab listening test of both VSSA channels. Measurements will follow over the weekend.

VSSA is a very, very good sounding amplifier, of course a lot of dependency factors included but if someone don't mess around too much, can definitely taste VSSA sound at its best.

Regards Andrej

Looking good Cat. Just neat. Congrats. Keep the Samwas cool a bit off that sink when you will wrap the thing up. They aren't bad but had a reputation for going rather soon in TFT screens PSUs at least. In Samsung stuff mainly cos that's them caps mom company.

VSSA once set (trimmers measured and replaced with resistors) holds on to +/- 1mV (true), needs no DC servo at all.

Samwhas were so cheap (1 €/pcs) that I couldn't resist them. Will place them away from sink as you recommend. For comparison purposes I'll assemble two PSUs with Nichicons and see how much better they're.
