I recently purchased a Buffalo 3 DAC Board, with the 4 channel SPDF board and metronome upsampler. My intention is to build an upsampling DAC - ie run my CD player and computer into the SPDF board, then into the metronome, then in the Buffalo DAC.

However the Metronome only takes I2S input, and the 4 channel SPDF board only appears to output SPDF (just to be clear, I bought the cheaper board that is available with the Buffalo 3, NOT the CS8416 board).

Is there any way to mate the 4 channel SPDF board to the Metronome?

Now for all those who will say that upsampling doesn't help - you may be right. But right now I do use upsampling everyday (I have an BB/TI evaluation boards for the SRC4192, which does accept SPDF). This cascades into my Cirrus Logic CS4398 DAC, also an evaluation board.

There is a much better ASRC built into the ES9018 than the SCR4192. Any signal you feed to it will be up-sampled already, so there is no real need to use the Metronome.

Brian thanks for quick response, do you know any more about this? I did not see any reference to this in the integration manual (I've read it twice already and intend to read it a few more times before I start assembling my DAC) so is sample rate conversion automatic? Does ES9018 chip upsample everything, if so to what bit rate/ sample rate? I didn't see any user settings on the Buffalo DAC dip switches for this.

If you haven't already, take a look at the ESS Sabre32 product brief,

http://www.esstech.com/P...20Rev%200.6%20110117.pdf

and their white paper (note, it is on the ES9008 chip).

http://www.esstech.com/PDF/sabrewp.pdf

What we do get is a dip switch setting to use or bypass the oversampling filter and reclocking in the ESS9018 (SW2 / 4).

I've had more than a few modded CD/SACD players and DAC's and I am very impressed with the Sabre32 DAC chip. Also impressed with the designs and reasonably priced offerings here at TP. My friend has a Wyred DAC with the ESS Sabre32 chip. I wanted more input options and felt the shunting power supplies would take it up a notch or two.
