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.

Don't keep everyone in suspense. Aren't you going to mention the response from the head of PS Audio when he suggested that you email him directly about your concerns. I understood from the PSA Forum that PSA was providing an RMA so that you could return the MK2 DAC since the product didn't meet your needs.

As an owner of the DirectStream DAC Mk2, I must emphasize how wonderful this DAC sounds. It is probably the best sounding DAC under $10K, and may even be preferred by many listeners of much more expensive DACs. It provides clarity and detail, but without any of the digital harshness that affects many DACs. Bass is deep, tight, and real. Soundstage is wide and deep. There is a smoothness and naturalness that eliminates listening fatigue. I have had my Mk2 for only two weeks, and it continues to get even smoother and more "real" sounding as it settles into my system. There is zero hum coming out of my speakers, even with my ear next to the speaker drivers.

Ted Smith, the designer of the DirectStream DAC, acknowledges that there may be some listeners who notice some low-level hum when putting their ear close to the DAC itself. Here are a few of Ted's comments on this issue: "The part that causes the problem is one part. The humming comes from more than one cap that it affects. We did a couple of board turns changing the layout and number and type of caps in this part of the circuit and lowered the hum level. Changing the design overall to totally get rid of the hum would have been counterproductive in overall sound quality." So sound quality is the ultimate goal for the Mk2 DAC, and it succeeds fantastically. Unless you listen to your music with your head next to your gear rack, this low-level hum is a total non-issue. And the Mk2 even has the ability to lift the ground on any input or output that might be contributing to an actual ground loop or other ground-related problem in a particular audio system.

I recognize your frustration in not getting a product that you expected would have a built-in streamer. I hope you find a DAC/streamer that you will enjoy.

My situation is a little different. When I bought my original DS DAC, I already had an excellent Innuos streamer/server and chose not to install the Bridge II to provide an Ethernet connection for my DAC. I knew from early information about the MK2 DAC that it would not include a built-in bridge, so that was never my assumption or preference. Knowing that periodic updates for the MK1 required use of an SD card, which was not a very elegant solution, I welcomed the ability to update the new MK2 via a network connection. 

Now that I have the MK2 and can listen to it in my system, I am very happy with how natural and non-fatiguing it sounds, while also providing realistic transparency and detail. It's a great DAC, and I'm sorry your situation didn't allow you to enjoy its beauty and musicality. However, there are lots of great DACs and streamers out there, and I'm sure you'll find something with the sound quality and features you're looking for.

@oczed  I enjoyed your post. A calm, logical response to criticism is always welcome!
