Anything wrong with PS Audio DirectStream DACs?


I'm counting right now 19 (nineteen) PS Audio DSD DACs for sale (new and used). Strange. Some second owners also selling... The reviews are unanimously stellar.

I wonder why.

I can’t seem to get much info on price other than it’ll likely be a $12-$15k DAC at least. The thing with Directstream that gives me pause is how high the THD has been measured in the past. I don’t know if these firmware updates are able to address the noise floor, but that’s one of the things that make it concerning.

Also, aside from the TSS DAC, there may be a DS 2 that’s a little more in line price wise with the original. 
I’ll say that looking at the amount of deals for DS as it comes to the end of its life cycle is intriguing. Network card installed with Windom for $3-4k.
Had the PS Audio. Kept it for one week, then resold it. The sound quality was poor relative to its price it my system. Maybe it would shine in another system. A Mytek Brooklyn and a Modwright Oppo 105D were superior to the PS Audio for me.
there is probably a Windom update coming in the next few months, their new transport is almost ready, and seems the TSS will be about $15-18K from what I've read...new transport is reportedly $6500...
I owned for a few years the PS Direct Stream Dac, sold it and bought a Lumin X1. Night and day difference in sound quality! I am now running it direct to my tube amps. Very pleased with the performance.

I hear a lot of good things about Lumin from the T2 on up. There seem to be a lot of people that love the DS updates though. What I can’t figure out is how much better can these DACs get and aren’t the diminishing returns quick after you pass the $5k mark?
