PS Direct Stream latest firmware, "Snowmass"

It’s amazing that they offer this magnitude of improvement for free...

Anyone have an idea what type of things Ted Smith is changing? Using a FPGA is it code that he is changing or reconfiguring the software? Still using Delta Sigma DAC isn’t he?

Check out the PS Audio Community Forums.  Ted has many responses there. Paul too

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

The DAC upgrades seem to be about once a year. This is my first upgrade. In my system I think it’s a terrific upgrade. Everyone familiar with my system agrees   The transport upgrades have been more frequent. To me each has improved sound but not of the magnitude of the yearly DAC upgrade
