PS Audio Direct Stream MK2 DAC

While researching the PS Audio Direct Stream MK2 DAC on the PSA Forum, I came across this:

"Regarding “hum,” Ted said: “ You had the opportunity to return your device if it was wasn’t acceptable. I don’t know how one could claim to have been screwed…….”

Not only that, this “hum” was a known feature, as it was discussed early and often in the beta thread. Paul even went so far as to claim every component PSA has ever produced (or at least, every component on his shelf) has this hum."

Further, Ted himself says:

"The hum is coming from the piezoelectric response from a few critical capacitors in the power supply. The device was designed with a component that wouldn’t cause this problem, but supply chain problems forced us to design in a slightly older version of the part which caused the hum. Unfortunately, the new and old parts aren’t footprint compatible, so we’re stuck with the older version for a while even when the newer parts become available again."

Ted is Ted Smith, the" Chief Digital Dude" at PS Audio.

Question to all PSA DS MK2 DAC owners, do you hear a hum?

All in all, do you think it would be better to wait for a while until the problem sorts itself out - OR - is it "much ado about nothing" and I should just go ahead and get the PSA DAC?

I am leaning towards waiting .... But I am interested to hear your views too.

I have owned 2 PS Audio products - first the DS Jr DAC, then the Stellar phono preamp. Fremer gave that phono preamp an excellent review and I bought it when they had a promo on it. He mentioned hum problems with it, which he said he was able to resolve, without explanation. I also had the hum problem. At some point one of the channels stopped working and I sent it in for repair under warranty. When I got it back I no longer had the hum issue, so I don’t know if they figured out a way to fix the issue and did it when I sent it in for service. I sold the DS Jr DAC about a year ago and bought a Holo Audio Spring 3 DAC. Even though it can’t be upgraded, I have been very happy with the sound and found it to be a big improvement. I don’t know how the Mk II DAC sounds, but I believe it costs about twice as much as the Spring 3. A lot of DAC choices out there these days.

I’m curious about the Air Lens streamer and have been waiting a long time for it to become available and see how it compares to the Lumin U2, another option I’m considering.
