Board also has its own low noise power supplies. Simply connect to a 9V transformer ( or 12V dc)

How does bbb handle 24 bit FLAC? I'm asking because it has only 10/100 lan the same as rpi. I have tried those files on rpi (squeezelite) and it can't handle it. The files have bitrate of about 4000kbps.

It's at track changing times that I dislike those DC pops the most.

Good to hear the noise floor is low, something other no-dac DSD thing-a-me-bobs have been suffering from. I wonder if the S03 is making the magic here, cleaning up unwanted artifacts in the bitstream. Have you tried, Amanero straight into the Direct-drive dac, I wonder what the noise floor is like then?

btw, if just looking for a native client for realtime conversion on Windows and USB play out, Foobar2000 will do this too. Eventhough HQplayer has many more filter/conversion options, it interface still leaves a lot to be desired. I wish it could just act as a driver and not just only be a stand alone application.

Unfortunately, HQPlayer (demo version) on OSX crashes!

Anyway, really happy with the results of the live transcoding.

Thanks for the comments - very exciting developments

No S03 yet, just straight from Amanero!

Tried Foobar initially but noise/clicks appearing even with native DSD

JRiver -fine but the transcoded DSD not up to quality

Best results coming from HQPlayer.

Fyi, this is my current setup for evaluation, using SE outputs:

An externally hosted image should be here but it is no longer accessible. Please upload images instead of linking to them to prevent this.


Keeping it 'simple' initially. No isolators/reclockers.

Next plan is to introduce "Digital Vol Control" so that the pots can be removed.
Outputs can be cap or transformer coupled if needed but at this stage keeping it direct.

Experienced some stuttering during playback especially if PC is just booted but after a while everything steadies out - so some startup procedures coming in already

Roon looks very promising, if a bit pricey. I'll probably go for Roon if/when it has the integration.

Thanks Ray, very interesting but cannot see any transcoding capabilities from PCM to DSD before streaming and what Fs max of DSD

You do transcoding/playback with HQ Player; work is ongoing to develop Roon so that it can act as the front-end interface to HQ Player.

Got it, thanks! It is all under their support FAQ and forum
And I am assuming Roon has DLNA support?
