I have been a streaming only fanatic for quite some time now. I do have a few hundred local files (albums) and maybe 30 or 40 DSD files on the Extreme. I NEVER listen to them.
I thought I would try the local files both 44.1 and DSD now that I have the switch (old card at the moment). I am BLOWN AWAY with the local file playback. I can see why many only listen to local files only vs. streaming. I am going to have a hard time now listening to streaming UNTIL, the new card is remedied, the Router, the TACDA card and the BPS cometh.
It would be so amazing if with all of the upcoming enhancements brought streaming close to local file playback sonics, which at the moment there is still a LARGE discrepancy in the sound.
Edit: It has to do with the MUCH lower noise floor, which seems non-existent with especially the DSD files, but also Redbook.
