For those of us who are interested in a mobile solution for native 24/192 streaming to an external USB DAC, this particular one below should be fairly simple

Since I'm Celadus in Computer Audiophile forum and have not seen much interest there at the time, I've updated infos only here lately and that thread is much more obsolete than this.
Now I've some good news and I've updated the title and OP (1st post) for DSD to iOS streaming, it's not polished since a lot of infos are obsolete, I'll do better next time when I'll check some more interesting things.
BIT-PERFECT DSD STREAMING TO iOS (using a DoPE server)
If you have a compatible USB DSD DAC, you can stream DSD natively (bit-perfect) to iOS without converting to PCM (which is not the purer or best performance path to follow).
A very important thing for wi-fi streaming is that
if you've set the server to convert on-the-fly DSD to 24bit PCM, you can't stream big DSD files (over 10 min) to iOS, with DSF files you can and with better sound!
Follow these instructions to stream DSD to iPad natively using JRiver MC 19 server (DoPE=DSD over PCM Ethernet) and 8player:
In
JRiver MC19 go to TOOLS>OPTIONS>MEDIA NETWORK>ADD OR CONFIGURE DLNA SERVERS... >ADVANCED (near the bottom) check "Bitstream DSD (requires DoPE compliant renderer)"
In iOS, with the CCK or LtUSBA connected to the USB DAC (iDSD), start
8player seek JRMC19 library and play DSD bit-perfectly!
I guess with 8player the iPad is a DoPE compliant renderer...
(NOTE= since JRiver server sends native DSD this way, you can't stream to a PCM renderer a DSD file anymore).
This trick should work with any DoPE server, just check for the specific stream setting.
I've tested only DSD64, but I think DSD128 should work if wi-fi isn't stressed too much.
Since wi-fi streaming DSD to iPad it's possible using a DoPE server let's seek a wireless storage portable server that can do it.
With my Seagate GoFlex Satellite DSF files are not even displayed in 8player.
Maybe the latest Seagate Wireless Plus 2TB can do it?
Anyone has one to check DSD stream to iOS using 8player?
