Well I fell asleep and 2 AM, got up and payed with all this until 6AM. Here is what I found so far.
First I tried the Lyngdorf ASIO driver. Sounded good, but I could tell by my ears and then neck hurt, it plays a little bright. This has always been a barometer for me, I can always tell. Next I tried Lyngdorf Wasapi driver and it sounded different , maybe better and definitely not bright. Then I switched back to the Lumin running balanced XLR into the Lyngdorf Analog module. I believe at least for right now this was the winner. I had all these set to DSD sampling, except the Wasapi which must not do DSD as it only gave me 384K PCM max sampling no DSD option…
Even though the Lyngdorf resamples to 96K to clean things up to run thru Room Perfect, in my mind the best possible analog or digital signal it receives and then does its internal thing the better. Listening to some you tube from Peter Lyngdorf and talking to somebody from Lyngdorf ,his internal processing of the Lyngdorf does no harm to either USB or Analog input.
Roon makes it pretty easy to sync the same music between all 3 sources 2 USB divers to the USB and the Lumin, and the ability to just switch back and forth between all 3 with the Lyngdorf remote and changing the ROON source. I was using the PC and Ipad testing all this and how they interact,also cool that it still picks up the Ipad as a end point I guess and I literally could be switching between the 2 USB and the Lumin analog and still be playing something thru the iPad speakers !
So that’s it for now, will try again
