Hi R&B ( cute, yes? )

Thanks so much for the Buffalo32S. It is remarkable. I am spending way to much time being astonished at how good my music sounds. I built a balanced to unbalanced converter to drive my tube integrated from the DAC. Terrific. Now when I get my Volumite I will try switching to direct amp input.

I know Russ was on the SMCWAA-G spdif modification thread some time ago. I also added a coax output but was not using the device much until recently. The combination of FUPPES, SMCWAA-G and Buffalo32S may become my primary system now.

I posted on diyaudio about my bit-perfect tests. http://www.diyaudio.com/...page=25&pagenumber=5 I hope someone else conducts an independent test.

I am connecting the spdif output directly to D2 on the DAC. I plan to install a switch to select between I2S input and spdif on D2 input. I may switch the grounds, too.

Of course some listening tests to compare I2S and spdif are in order, but you claim the SABRE chip handles both equally as well.

Also, I made a small change to FUPPES transcoding of flac files, and it reduced the CPU overhead dramatically down to 1% - 2% or so. Here is the current flac portion:

file ext="flac">
<type>AUDIO_ITEM</type>
<mime_type>audio/x-flac</mime_type>
<transcode enabled="true">
<ext>wav</ext>
<mime_type>audio/wav</mime_type>
<http_encoding>stream</http_encoding>
<decoder>flac</decoder>
<encoder>wav</encoder>
</transcode>
