PS Direct Stream latest firmware, "Snowmass"

I own one since product’s inception & have no financial interest in PSA.  That said, I can’t remember how many FPGA upgrades with dramatic quality enhancements I have received....for free. In my system, to my ears, this one (Snowmass)  is a true quantum leap.
So, if you are interested in a new DAC, read your buns off about this one and the rest and compare like the dickens.
But, if you really want to BUY a new DAC, I recommend you hear this one in your system (needs 400 hours or so) and, in my humble but deeply experienced and committed opinion, you will know.

Ditto, my advice and experience track with yours. I have no financial interest either. Simply wish to steer other music lovers in the right direction. 

I have been using a DS JR for quite some time and have enjoyed it with Huron and then Redcloud. In fact, I recommended this DAC to many, and I bought it new for a great price. I decided to buy the full on DirectStream (Senior) last week at a great Black Friday deal (free bridge and the $2k off the DAC that is on special now). When it arrived I listened with Redcloud as that is what I have been listening to for months with my Jr. WOW WOW WOW, what a jump in performance from the Junior. Much more open, more organic, more analog and never a hint of harshness. I then loaded Snowmass and well, game over. I do not see how it can get better. The sound is incredible. Detailed yet never harsh at all, wide open soundstage, meat on the bone but never thick or mushy. Someone above said it, like listening to a master tape. I am so happy I went with the Directstream Sr, as at $3999 with bridge I can not think of anything that can beat it. I have tried low end dacs, mid range dacs and uber high end dacs. Nothing even has come close to this. Anyone that wants a solid dac with addicting gorgeous sound, that is upgraded by PS Audio every year, take a look at this one. Seriously guys. I think they have them on sale at $2k off through November. If you call around you may get an even better deal as I did.

and it gets better with a few hundred hours playing music...

I saw the $3999 offer on the PS Audio web site but the bridge was another $800 or so extra.  Where did you find it at $3999 including the bridge?
