PS Direct Stream latest firmware, "Snowmass"

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 

I own a DS and upgraded to Snowmass.....
The upgrade is an improvement. A nice one and I am very happy. "Is it that much better?" No of course not. The DS was already a wonderful DAC and the improvements are incremental. But it is easy to get excited when you listen to say a Simon & Garfunkel recording that you know in and out, and hear the clear chunka-chunka of a rythm guitar you never heard before.... yes you knew it was there, but now it is a distinct instrument. For this, we audio nerds get really excited.
Regarding the upgradability of their DS DACs: what is there not to like? But, don’t assume it is charity. With each new release, they get press and more sales for virtually none of the investment of a new product. Ted does not get paid to do the software development but makes money on sales. At some point, the development will stop....even if this new upgrade is the last one, I am very happy as it is. Personally, I suspect there are more gains to be had by upgrading the analog amps.... but that is just my assumption.
There are few hi fi products I have purchased in the last 40 years that I have been very pleased with... this PS Audio DS DAC is one of them.

I think they are running a sale right now.... you should check it out.

Viewing the PS Audio Forum, I don’t think there has been a single person that is not satisfied about this firmware upgrade. Excuse me, not just satisfied but raving about the improvement!
To me, it’s almost like listening to the original studio recording.
Thank you PS Audio.
