i have one running in my dac right now with the parts your recommended and it s seems to work well. and 5v is pretty much the lowest i can go to adjusting the trimpot.

I have Googled and found a sigma11 by AMB laboratories. If you are referring to that one, its a serous power supply. Has extensive technical documentation. You had no slouch of a reg before.
yeah i ve built a couple of the sigma family psus because it performs great, has great current capability, i can switch voltages from 36v to 5v when used with sockets, and finally because the designer offers great support and isnt after money.
i was wondering about the powering digital circuitry because i tried the ikoflexer-stormsonic 3.3v reg (http://www.diyaudio.com/forums/powe...ake-discrete-shunt-voltage-regulator-114.html) with for a clock and a receiver chip (just to see) and didnt get good results at all. i guess thats what happen when you use circuits not for the purpose it what intended to be used for.
i just wish a 3.3v SS1.2 could be made. i know someone earlier said he was going to experiment on this (fred?). maybe he could join in?

Nice result!
yes. more air to the sound,more soundstage, more smoothness, more detail, and the list goes on! and that is without remote sensing.
really this reg is growing on me and make s me want to sleep with it right next to me.
This surprises me. Something must have been wrong with the construction I think. I never built that circuit but it looked pretty good on paper and stormsonic had good results. What were the negatives?
with the clock i was hearing weird kind of echoes and for the receiver nothing was wrong but the performance was clearly better with the sigma or flea. i ve checked my wiring and everything seems fine. i m using bc560c for bc857, 2sk170bl for jbf862 and a mpsa18 for bfr92p. also i omitted c3. anyway, i ll do more testing.
on a side note: on SS1.2, i bypassed c2(vishay mkt but still) with a ft-3 russian teflon cap and the result TO MY EARS are quite stunning. now i dont know how it measure. but to me clearly it sounds quite a bit better. maybe it s not the right way to proceed but it might just be that the benefits that this cap brings outweight the drawbacks.
