Testing of some PCBs. I've to say I'm very happy with the quality of these PCB from Olimex.
 
The one with the big heatsinks is based on the soha II buffer. Bias at 75ma for now, I'll double it later on. Regulation at +/- 14.5V by two LM337 (I had no more lm317 on hand and little patience...).
 
The smaller board is an opa134/tpa6120 preamp (tpa6120 inside the opa134 feedback loop) with onboard lm317/337 regs (giving +/- 11.5V). There's still an empty spot for a DS1802 volume control. It's also a quite decent headphones amplifier (listening to it right now). It's a development of this: http://www.head-fi.org/forum/thread/544117/i-v-stage-for-pcm1794-8-tpa6120-preamp#post_7343784

So incredibly understated and elegant, very much to my tastes. I love it!
