Ditto, been wanting to try out the counterpoint and was going to order a volumite anyways, so two birds one stone!
New to DACs
Hello Forum,
I would like to take a DAC project and have seen that the Buffalo could be a nice solution. I would like to also consider using a tube output.
I would like to ask the members of this forum for some advice and/or clarifications. Keep in mind that I have little if no knowledge of digital circuits.
1. I think adding a tube buffer stage is feasible since I see that the Buffalo has a current output (from the DAC). I will only have to not use the suggested (or use - dual output) "IVY".
2. Reading some feedback on this forum (there is a lot to digest) I have a doubt for the performance of this DAC in SE output. I would like to use a 2c51 dual triode as a buffer but some here have expressed issues with SE operation (but not really explained which output was used (IVY or other).
This is all (for now). Thanks for the patience.
Cheers,
MV

Re: tube I/V
Greetings MV,
As a fan of triodes, I'm prompted to reply. I believe any reservations you might see relate only to the significant advantages of balanced designs and not to any particular problem with using the circuits in single-ended mode.
Regarding the dual triodes, I know that when they sound good they sound *very* good - especially when nice and hot. However, I retired my equipment when it became nearly impossible (or ridiculously expensive) to find tubes of the quality I learned to love. Now enjoying the advantages of balanced gear, I am happy to have switched!
You might look at this thread: http://www.diyaudio.com/forums/showthread.php?s=&threadid=107538&highlight=
While other vendors offer I/V kits using dual triodes, remember that one of the main points you will read here is that the exact circuit details are very important with the ESS chips.

Russ/Brian,
Is there much of a difference (sonically) between that older (beta-beta) counterpoint and the one now in stock?

Got the panel for my Buffalo build last week. There are no LEDs in the holes, but you get the idea of it:
The Hirez input is for DSD from a modded Denon DVD.
I apologize for the messy and dirty table 🙂
An externally hosted image should be here but it was not working when we last tested it.

Well with the current design the input impedance stays lower, and it has a couple other advantages. It does measure slightly better.

Hi Mr Majestic,
How much did you pay for your customize panel? And to whom did you outsource?

Re: Panel
I'd have to get back to you on the cost. It was at least €100 for both back and front. Front Panel Express made it.

MrMajestic,
It looks great - I would say majestic!
So what's inside? 4:1 MUX (+ 2 x Toslink modules) / Otto / Buffalo / IVY / (JT or Volumite?)
Cheers,
Nic

Thanks 🙂
2x coax + 2x optical toslink -> 4:1 Mux - > OTTO -> Buffalo w. volumite -> IVY

Well I would just use an LCDPS (or some other 5-7V regulator) to feed the digital side.
Then you will need some sort of SMPS or DC/DC converter to get +/- 12-15V for the analog section.
Pretty straight forward. 🙂
Cheers!

You will need an SMPS to generate a bipolar supply for the analog sections. Ideally you want +-15VDC, but can get away with +-12VDC.
The digital section needs +5VDC or so.
Magsy said:
Yes, should be fine. But I would probably want to use a bit beefier supply, or at least plenty of capacitance after it. I would shoot for .5A.
Cheers!
