PMG 512 DAC first impressions

@tomhail I’m one of them you’re probably referring to. Most of my comments have been general b/c I’ve been more involved w/trying to get the streamer to play nice with my network. So, I should post re. the sound. Up till now my comments have been “great”, “love it”, etc.

Background: Started w/the DSD Sr, moved to the MK II and now have the PMG 512. Coming up on ~4 weeks w/the DAC.

Out of the box, noticed fine details in recordings and better bass (tighter, more refined). Bass lines of upright, electric and drums are solid and so well defined. I know other’s liked it but I mostly felt underwhelmed w/the MKII bass. PMG…sound stage, wide but, more importantly, DEEP. Instrument placement is the most pinpoint I’ve experienced in my house since 2009. And, dynamic. The range is noteworthy. The first 2 tracks I always play are Bonnie Raitt, So Close, and Dire Straights, Private Investigations. Bonnie for female voice, cymbals, guitar, drum, speaker placement vs. spatial cues, but mostly for her voice (see comments below). Private Investigations, the culmination of everything to judge by. Quite, loud, depth, width, micro details, pace, male voice, guitar, etc.

I was so impressed with the 512’s sound that I purchased the PMG Pre to replace my BHK. Wow, it got better. First thing I noticed was the dead silent noise floor. There’s always a bit of very low level tube hiss w/the BHK. More, or less, depending on tube rolling, but always there. With the BHK sidelined I was able to hear (actually, no longer hear) how much underlying din there was. The PMG combo is dead quiet. There’s a 3 dimensional quality that is now the new baseline. When a song fades out…it trails off forever. Also of note, amp is the BHK 250, tube’s, too, and they’re dead quite w/this pairing.

I have Roon streaming random tracks as I type this. Lyle Lovett, Smile, a slow jazzy tune, just started playing. First instrument that comes in, piano…so realistic and each note defined. I’ve seen him 6+ times in concert, this is the closest I’ve heard his voice to being there. Cymbals…nice tsss and decay, bass…tight, drums…taught and clear, strings…sweet. Now, Diana Krall, Let’s Fall in Love, is up. Her voice, again, best I’ve heard. I’ve always believed female voice is so hard to replicate. There’s a chesty characteristic that I cue in on. The PMG DAC (and pre) has none of this. Just, pure, voice. Next up, Chuck Pyle’s playing, Rio Rey. Colorado folks should know him. Never made it big time but he’s about as good as it gets. Such a pure voice. Fabulous on acoustic guitar and the fiddle in the background…again, so clear and realistic.

Also, I feel, PRAT is mo’ better. Synergy, timing, pace, toe tapping, etc. is next level. If I had to pick, soundstage and dead quiet noise floor are such an improvement over previous products. But, everything else I described deliver in spades with this DAC…complimented exponentially (by how much?) with the PMG Pre. I’ll agree w/Paul that I do get “jaw dropping” often.

Speakers, Polk Audio SDA-SRS 1.2tl’s. Whoa, wait, don’t stop reading!!! Fair to think Polk isn’t in the speaker league of many of you. I know I’ll get some push back and pooh pooh’s on my speakers but these are not OEM. There’s a serious upgrade community…crossovers, inductors, internal bracing, dampening, tweeters, outriggers, etc. and, since 2009, I’ve transformed them to a level most ‘audiophiles’ won’t think them capable. Not as modern and resolving as today’s speakers but the soundstage they produce and, post mods, the detail they have is astounding. I’ve been to Munich Hi-End, Capital Audio Fest, etc. auditioned uber speakers and have background selling audio equipment. If you haven’t heard my set…you simply don’t know. Not saying they are giant killers but they hold their own. What I’ve learned in the past 10 years (start of my foray into PS Audio) is they dramatically scale up with the quality of gear. I haven’t reached a point they just stop delivering. PMG DAC and Pre combined w/the BHK 250, anchored with the P15 Powerplant, is very satisfying.

Next move, in the wings (pun intended) are a set of Genesis Gen II’s that are, if you don’t know them, of the same Infinity DNA as the IRS’s Paul used to voice most PS Audio products prior to the FR series. I have a pair Paul helped me get several years ago. New Year’s resolution is to finally get them running w/PMG gear running them. Long, long-term, the FR series is under consideration.

My .02 cents. PMG Series, winner, winner, chicken dinner.

Yes, I followed your journey in receiving the IRS V’s (if my memory is correct). If I recall, you are an Air Force vet like me. Thanks for the detailed description of your adoption of the PMG units. I am hoping to one day replace my BHK pre with the PMG pre.

Good memory. Not IRS but Genesis Gen II’s. Smaller of the 2 sets Paul and Arnie created back in the day. Yes, AD retired Mx Analyst. Go Blue!

BHK is no slouch. I kept my pre and probably won’t part with it. Same w/the 250. I love tubes and have collected quite a few since 2019. I’ll always have a second system and having BHK at number 2 is kind of gluttonous….but, whatev. LOL.

After getting my replacement unit, I’ve been quite happy with my PMG 512 DAC. One additional step that I will need to take is to reassess my speaker/dual-subwoofer alignment/settings in order to maximize sound quality. I’ve pretty much gone through the steps with every DAC purchase as each have different sound characteristics. Even though it sounds much better than my MKII, I know it will be even better in the end.

Got my 512 DAC yesterday and running it in now 24/7. Out of the box is airy and detailed over the MKII. How long it took for you to burn in ?

200-300 hours but most done in the first 100 hours.

Which ‘zone’ would be best to plug my PMG DAC i to on the back of my power plant 10? Had it in “High Current” Zone up to now, is that right?

I assume the PMG DAC does NOT use a lot of current. Amplifiers use more current.

still running it into 100hrs as well my ears haa haa.

The internal streamer fidelity is top end, comes almost close to RS130 w ext 10mhz clock.

However, the software requires bug fixes and full regression tests. It fails at simple tasks.

When i move out of uPNP using JPLAY to Tidal connect, i can’t switch back to uPNP, unless I restart the streamer.

All zones on the P10 are the same only the zones marked High Current have an in-rush limiter for the power up of large amplifiers. You should group analog devices together in one zone and digital devices in another (separate them)

ok that really was my question - am running my BHK directly from wall currently and will group digital sources (DAC, streamer, PhoenixNet, TV), together not on high current and try the BHK amp there.

P.S. My PMG DAC has really come alive in terms of the drums’ soundstage - at this point I hear the kick pedal or snare and think ‘wow, that’s right there in my wall’…. been playing alot of Led Zeppelin, forgot what a good wife repellant it was…she sends me texts when I am needed because my man cave is impermeable to sound! used Octave records’ percussion sacd to fine tune my speakers and the REL tracks for my pair of RELs again. Now dialed in and am wowed by the PMG DAC.

Really? That’s saying quite a bit!

As usual.

Totally agree on internal streamer - absolute detail using Qobuz - Innuos Zen Mk3 almost superfluous. Love it.

What external clock do you use, if you don’t mind sharing?

Are you disconnecting from the DAC streamer in the Tidal app before going back to DLNA? I think Tidal Connect does audio device locking where you have to manually disconnect.

New streamer firmware update is available.

I was on the phone, yesterday, with the software guru, Peter. Great experience/guy. Don’t press me on specifics but he mentioned there were updates that would help you guys w/streaming subscriptions and, I believe, UPnP/DLNA.

We worked on my network issues and Roon. I don’t stream outside of Roon…local library. I’m the first person he used the new remote access to help troubleshoot. Very helpful and really able to get into the weeds on my network.

Re. the firmware, he said I’d be fine but I’m gonna hold off updating b/c we applied some network changes that I want a few days to test. Here’s the new firmware:

I didn’t have such a problem with other streamers. Maybe PS Audio can clarify how to switch between apps.

I updated to d2261a FW and let me try your idea.

Update: So far it works. will try more tonight. Thanks for the tip!
