^^ What Chris said. I am very fond of the SSR03, but I haven't tried an sslv in this application. As the board contains LDO's powering each critical section, it may work just fine.

Thank you both very much for the guidance!

No worries D-Mike - we're happy to help.

Chris1967 came by my place tonight and we auditioned his Soekris DAC on my main system. As transport we used the new Raspberry pi2 with a selection of classic and jazz music up to 24/192. We played only through the unbuffered outputs. Stock filter too.

The Soekris is melodic, has a nice sense of flow and natural timbre. As minor faults I would point out the not granitic bottom octave and a small lack of air in upper mid-high frequencies. Definitely far from the typical ΔΣ sound.

Dedicated output modules should be on the menu, which ones is still under investigation. Tomorrow we will put it up against the Marantz HD DAC1, Pioneer U05 and Audiobyte Black Dragon..

The filter swap is a must!

MisterRogers · « **Reply #65 on:** March 21, 2015, 10:57:43 PM »

Agreed - a couple of the most recent filters are quite an improvement

Yes, Chris intends to swap the filter soon, probably will go for the CrapMagic one.

Isn't the SSR03 a massive overkill here?
I am just wondering if same performance for this job could be done in a smaller footprint.

It very well may be. Over the last few years I've taken to providing the very best, appropriate PS; even more so if digital circuits are being powered. Too many times working up the ladder with DAC PS's - in most cases hearing a subjective improvement. It may not matter in this application, but it's mattered in most.

Fair enough. I will try my own ladder up. It looks though that i won't escape from the Ref-D's.
Recent developments in battery banks have made me think of portable R-2R. The Dam footprint is smaller than i anticipated at first.
