Do you think the problems you heard were inherent in the streaming itself, or could it have been Direct Sound? Like I said, direct sound, when it is upsampling, is audibly changing the sound. But when I was able to stream things correctly, I couldn't measure a big difference (I did measure a difference though, so I want to be fair about this). \n\nI haven't had enough time to really dig in myself, I've only listened a little bit. Some on speakers (The Revel's that James reviewed) and some on headphones (various good headphones) through either the MOTU interface or my Cherry setup. Sometimes the sound was good and sometimes not so much, and that was what lead me to realize just how serious this directsound issue is. \n\nI'll work with Gene to see if we can get anywhere, but companies like Google, Amazon, and Apple have not been easy to work with. They usually ignore me. \n\nMatt\n\n\nI assume Amazon is getting the same files as the other streaming companies and aren't intentionally changing anything, so sound degradation I hear is due to Direct Sound. \n\nHow exactly were you able to stream bit perfect correctly avoiding resampling in Windows mixer? I have thought about using the WDM workaround in JRiver but have not had the time. It is frustrating because it should not have been that difficult for Amazon to enable Wasapi exclusive mode. It could be turned off by default for customers who do not have an external DAC.
