Received my SOTM SMS-200 Ultra Neo with Clocking input option.. Burning in 3 days now ..  Using it in my intel 6700k Hqplayer Server with the SMS-200 Ultra Neo replacing my quad core fanless mini pc as the NAA. Prelim Observations:- 1. Getting Hqplayer to 'see' the Ultra Neo is a trying experience! 2. Your network has to hv good Ipv4 connectivity.. Ipv6 not supported by the Ultra Neo 3. Start up Hqplayer AFTER the ultra neo is on HQplayer NAA Mode. 4. I had great difficulty getting Hqplayer to see the Ultra Neo .. finally i decided to use my Minipc to connect to the Hqplayer and my iFi iDSD BL DAC! After that leave the DAC powered on And just plug the dac into the Audio USB port of the Ultra Neo. The NAA box in Hqplayer recognizes the Ultra Neo if you run the settings again. 5. Then i got Dsd256 to run .. occasional stutter but listenable. DSD512 NO! Crackling and stuttering!! 6. SOTM Thru their local agent advised the following settings 7. Works but not my preferred xtr-2s settings. So i experimented with the iFi iDSD BL ASIO settings. But How do u set this when the SOTM Eunhasu OS does not have settings for the DAC under the NAA setting? i had a brainwave !! connect my mini pc (win 10 OS) back to the iFi DAC, call up the iFi iDSD ASIO Settings put the buffer settings from low latency to Safe on 32000 byte buffer size! 8. Connect the ULTRA neo and cycle thru Hqplayer settings .. The Ultra Neo with the iFi iDSD BL comes on (NB YOU HV TO leave the DAC POWERED ON to preserve the Asio buffer settings!!! ). ---'Dont forget the Turn the volume of your DAC or Preamp to minimum.. u will blow up your speakers or your Headphones otherwise! 9. Still a bit of crackling noise and stutter on xtr-2s .. shrt mp -2s works just fine 10. Back to my Win 10 minipc and change tge ASIO setting to extra safe.. 11. Ultra Neo now works on xtr-2s now. just a little flutter now and then? 12. A liitle disappointing as my minpc allows low latency 33k byte buffer size and smooth playback! ? 13.
