What is the new clock? Looks pretty big in size on the picture - http://twistedpearaudio.com/images/digital/buffalo32s.jpg
OK, I was wrong - there are more registers but you don't need to touch them.
For the clock, I guess Crystek CCHD-950

Does the Bufallo32S accepts 24 Bits on I2S?
I use a Juli@ card with I2S out.
From what i heard the Juli@ doesn't support 32 bit, so it won't work with a Bufallo 32S on I2S?

Brian/Russ, apologies if this is a repeat question, but what are the dimensions of the new Buffalo32s - because there is such a lead time (on custom cases), I'm case planning and ordering tomorrow.
Many thanks,
Russ

Firmware
.
When one buys firmware . . . What do you actually get ?
I ordered some things including firmware, the package came.
I got all kinds of goodies, boards & components
but as I don't know what form firmware comes in I have no Idea whether I got it or not ????
can someone enlighten me please
thx

The firmware is an 8-pin dip chip and comes in a separate pink antistatic bag with a dip socket (sometimes in the same bag as the Volumite).
Sorry for not answering in the first three minutes. 🙂

If you want to be sure, and use a output cap with the buffalo32s, what should be the value? I see people use values between 0.47microF and 4.7microF.

Unless you are playing DC samples there is no need for one, but if you want one the value will depend on the load. Google "RC filter". But usually 1-2uf suffices.
Buffalo32S Test Results
So, here it is folks. 🙂
I have for you the first measurements for Buffalo32S. 🙂
Naked board no case or any shielding.
I am very, very, pleased.
I could have achieved a bit better DNR if I used some more aggressive filtering, but the trade off would have been higher output impedance. All in all I am extremely happy. Especially since you can drive headphones etc directly from this DAC.
For instance the ESS demo board measures slightly better, but has a very high output impedance. That's the trade off. Now if you drive cables with a high impedance and have to add an additional stage to drive your headphones you will probably end up with for worse spec then if you went directly out of the Buffalo32S. 🙂
Anyway I am very very pleased.
127db DNR is perfectly fine by me. 🙂
I enjoy listening to it much better than measuring it.
Cheers!

Single Ended Output

Single Stage Differential Output
-129 -116 -117
Normal Differential Output(low impedance)
-127 -118 -117Cheers!

mmm - very impressive that ur 20kHz Figures are the same as 1KHz
Can I ask what power supplies you used during this test and what is the current status of placid ?
can't wait to hear it

Thanks.
Huge kudos to Brian for getting the prototypes done so quickly. It would not have happened without him there.
The supplies were bone stock LCDPS and LCBPS. 🙂
Placid works well and I use it form time to time, but it still needs some redesign to be ready for the public. 🙂
I will keep you guys posted on our site about Placid.
Cheers!
