Yes - indeed it takes care of it quite well.

In any case there is no reason the effective jitter should be worse than that introduced by a digital isolator (carrier frequency aliasing) or processor such as XMOS. You can also tweak kernel configuration to your liking.

In any case - it works and sounds great!

Could you make stand alone active speakers this way, you would have to stream 1 channel to each speaker?
You might - but what I would do is use a single rpi and use my teleporters to move the signal to two mono DACs. That would work quite well.

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?

That looks like a fine DAC, similar to my COD.

I did not link to my DAC btw. I only mentioned it.

The B3SE has been measured, I am not sure the RPI-DAC has been. I would be glad to compare results.

The B3SE is also very flexible - allowing for multiple inputs and output stages etc.

I am sure users could be quite content using either DAC.

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).
