Who buy PS AUDIO ?

I auditioned the DSD against my Audio Mirror Tubadour III SE DAC.  The DSD sounded nice and I thought the build quality was great. After a couple of weeks of A/B testing, I came to the conclusion it wasn’t $3+K better that the Tubadour by any measure.  I returned the DSD.  

I had a P-300 power plant - their first regenerator.  Class AB power supply and balanced at the output outlets. It was excellent.  It eventually failed after several years.  I then bought a P500 that didn't not have an class AB power supply nor was it balanced.  I didn't think it sounded as good as the P300.  the P500 failed after 2 years.  I bought a Power Plant Premier, It was better than the P500, but still not balanced, not class AB and didn't sound as good as the P300.  I can't speak for the newer class of regenerators.  

I have a BHK 250.  It appears to be very well built and sounds superb in my system.  I am very happy with it.

The DS dac is a fantastic product that offers better sq and features than 2x or 3x more expensive dacs. Sometimes, When you hear people indicating that they didn’t like the DS they were using an older firmware release and this makes a big difference. To me, each firmware update raises the sq, and it’s damn good to start with.
As for features, who else has network (Ethernet) input, i2s input, free firmware upgrades, can easily drive an amp without using a preamp, MQA support, Roon endpoint, and it’s FPGA based? 

Overall, I think the BHK gear is pretty good value for dollar.  I run the 300 mono's driving some TAD CR-1's, and it is an outstanding match.  I have tried a Luxman M900u in their place, and it is not the right match with the TAD's, IME - - I like the BHK mono's better.  (I do think the Luxman is a very fine ss amp, and with the right speakers could be heaven...)

I used their BHK preamp for 3 years and it is sitting on the side now only because I nabbed a used ARC Ref 40, which does best it be a bit, but does not embarrass it.  The BHK ushered out a VAC Ren Sig II, sounding convincingly clearer and presenting a larger soundstage.

I used their initial P300 regenerator back in the late 90's and early 00's.  It softened stuff too much, IME.  Recently I used their P10 regenerator, and now use their P20 to power all of my electronics and they are worthy, indeed.

Their customer service is tops.  They will make you happy should anything come up.  And I find their gear works some sonic magic, when put in the right system contexts (horse for courses, of course!).

Stellar Gain Cell (preamp) & S300 amp.
Then I got the newest P3 Power Plant when it came out. Plenty of juice for both. I wasn't impressed by the internal DAC so I traded in a bunch of unsellable junk and got the DirectStream on Black Friday sale for $3350, no bridge thank you.  Best money I ever spent on SQ.
We heard the IRS Vs at the old plant. Will go back with different  music. Very impressive. Paul did play Thanks To You and it reminded me of the Earthquake theater experience. And the woofers have been replaced since then. He went with the same ones I found after welding my OEMs They played ithat track last year in the Carver room and it sounded like Sunfire hemorrhoids.
