PS Direct Stream latest firmware, "Snowmass"

I don’t own the PS Audio piece, but I have owned some PS Audio stuff in the past, including. DLink DAC that I just revived to good effect to pair with a Bluesound Node2 in a HT System, and I have a healthy respect for the company.  I am also not questioning the perceptions of the OP.  I note, however, that others have made similar posts about PS Audio firmware upgrades here in the recent past, with each new upgrade prompting some comments remarkably similar to the OP.
  So my question: is it really possible that each upgrade is really that much better?  That every few months PS Audio unlocks some new secret of Daiquiri?  Or is it more likely that the upgrades are different, emphasizing different characteristics, and on some people’s systems suddenly hitting a sweet spot that is system dependent?  I’m just curious what PS Audio owners think.  I don’t have an agenda here

+1.

Does Snowmass fix the clicks and pops between tracks of different format or sample rate? 

Or does it try to hide the problem by lowering volume?

this is discussed at length on the PS A forums with lots of input from the designers.  Too much to summarize.  I have never had that issue.

Ditto, never had that issue.

Upgraded to Snowmass, and there are some improvements but it isn't day and night in my system.   Still like RC a lot.  Never had the problem with hash or edgy vocals with RC.  On some discs, still like RC better.  It might be that I am just so used to hearing RC.  Will definitely do more listening this weekend.  Just the fact that you can upgrade or change the software is really a brilliant feature.
