I covered your first question earlier.

Yes - you can supply the pi from the P5 header. I would not necessarily use Placid. You will need to supply 700ma or so.

Russ, did you try outputting DSD?

Thanks,

Not yet, but I believe others have.

Russ,many stability, gapless playback, pop sounds or noise issues?
That's a great idea!

I have had some minor issues with using the device as a apple tv appliance, but none at all when streaming from NAS - even at 192khz. It works flawlessly and sounds superb.

But if the p5 headed is connected to the dac board, then is power coming from there too?

This would be the simplest option but the pi might inject noise back to the b3se.

If not, then a simple 7805 for the pi should be enough right?

Any PS rated for > 1A *should* be just fine if properly heatsinked.

I have been powering mine through the usb connector as usual, but I am working on a board that will likely incorporate a 5V supply - as well as other goodies.

Will this board be available in the future?
Is it some sort of backplane board where all the other boards plug into? This would be really aweome!!!

Exciting stuff.

Hopefully this board will allow full control of some of the Buffalo DACs (in place of the unavailable AC2).

I have exciting news there too!

Look for another thread coming soon. I actually have something far better than AC2 already working. Brian and I are just finalizing the design.

Here is a teaser...

Cool !!! Great application would be a audio video player. If a video with multichannel audio is played, will the buffalo 8ch do the rest ? I don'e see any HDMI to I2S adapter coming.

Best Regards,
Davide
