Okay, I read the complete topic of the buf32 and I have a few (nooby 
)
questions :
-For the power supply I could use 1 Placid powesupply for digital section and 1 bipolair version for the analog section ?
-would the digital section with it's own onboard regulators benefit from the placid or should I change them to shunt types ? ( I still have a few Dexa regulators)
- The analog stage has no onboard regulators ?
- Opamps are used for the I/V(?), why not discrete parts in class A mode, is this working better ?
-I have interest in buying this cd transport :

any comments ?
Thanks in advance ! Erik.

Yes. Extremists might consider two Placid BP for the analog section.
Have a look at the Tweaking Buffalo thread. First thing to try would be leave the on-board regs alone and use the Placid.
Wait for a tweakers version if you don't like op amp's.
Looks interesting!
Hi Russ,
I guess there are many of us wishing that wonderful Tweaker's board... any news would be great !!

Hey guys.
I am working on it. I redid the layout for 4 layers. And added some options around the clock.
I also added some coolness around AVCC.
Its just harder to find layout time these days with the new job.
I do plan on ordering PCBs in the coming weeks.
I am sorry for the delay, but the board will be better for it.
Cheers!

for me, 
there is a rumour that the new boards will have a pink colour. This according to the result of "the latest poll" subject "what favourite colour will your next board have".
A couple facts about the new Board:
1) 8 separate pluggable VREGs
2) Seperate output stage(s)
3) Some reworking of the supply routing for better RF isolation.
Otherwise its very similar to the Bufallo32S. 🙂
I am working hard to get it done soon.
There are actually three new modules I need to design to support this effort.
1) The DAC itself.
2) Some cool little VREGs(More about this later).
3) IVY II - This is actually done but being reworked to better fit a possible new form factor.
Also Counterpoint II is in the works.
And the very remote possibility of a tube output stage for a little fun.
Cheers!

Is this in reference to the tweakers board, or to a new version of the 'standard' B32S board?
