I've done some experimenting with upsampling my FLAC files to DSD using HQ Player; my atom processer based computer couldn't even deliver DSD64 so it's unlikely a BBB will have sufficient processing power.
On the other hand, using gigabit Ethernet connections I have rendered a DSD256 .dsf album on a BBB/Botic (ie, no upsampling, just simple network playback) so it looks like a BBB might be upto the NAA component in a HQ Player setup; I've recently purchased a high spec workstation to explore this further (benchmarks at around 9000 so should be good to upsample to DSD256 - should know pretty soon). I want to try loading the HQ Player NAA component onto a Botic/BBB to see if that is a viable set up.
Since the BBB is in the picture above and we need a source to playback DSD, I hope we can stray a bit off topic .
Continueing here..: I was looking at HQPlayer last night as well, impressive set of conversion options.
Just to keep myself honnest I doublechecked the specc's of the BBB and it Ethernet adapter only supports 10/100Mbps. It's important to remember to deduct a healthy portion off for overhead. Most adapters only achive a mere 60%-80% of actuall application bit rate, worse if other chatty applications are present.
@Acko, you were hinting at the DC offset. What are your thought on that, now that you've spend some time on the board?
