PS Direct Stream latest firmware, "Snowmass"

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.

Hate to be a party pooper, but this is same old story as every firmware release.

I upgraded from Redcloud to the T+A Dac 8 DSD, a DAC with a $2,000 less msrp, and it eats the Directstreams lunch in every way imaginable.
