Brian, I do understand that’s your point-of-view for reasons that are important to you. I’m sure you can understand that it’s more concerning for a number of PMG 512 users that DSF streaming doesn’t work than that the display looks wrong. Both require fixing, of course, but the relative importance of the fix depends on who you are. It’s quite likely the case that Roon-ready certification is important to a larger number of folks than UPnP and hence a priority for PS Audio, but that doesn’t make a streaming failure less important to me than Roon certification to you. I’d rather PS Audio fixed my issue first, though I can understand why they might not.
Paul might have alluded to, or was interpreted as alluding to, the UPnP DSF issue as being an edge case, but it isn’t. It always doesn’t work, rather than failing infrequently because of an unhandled edge case. Calling it an edge case is just obfuscation.
I may have misinterpreted but in the earlier part of the thread I read “edge case” as “statistical outlier”, i.e. not very many units had the problem (rather than how often the problem occurred in a given unit). I think what’s of interest is the percentage of 512’s with this problem. PSA has a much better estimate than we do and I expect we’ll not find out.
And yes, whether you are the target of the problem or just an observer makes a big difference.
I had also thought that Edge Case is an outlier (fluke or one-off), but doing some casual research the term is typically used in software to mean uncommon or unexpected conditions. This would mean that a listener would use the DAC in an unconventional way or operate it in a particular fashion that was not accounted for in the design.
I was a systems programmer for 40 years, and that’s pretty close to what it means to me. Usually, an edge case is infrequently tripped as most or all common and expected cases have been accounted for in the design.
Chris, I hope I never suggested the UPnP DSF was an edge case. That was never even in the topic I was responding to. Your issue is something we are currently working on fixing and, frankly, something we were unaware of and was never part of our testing protocols as no one at PS ever does this.
Now that we are aware of the issue we have an engineer on the case and will solve in an update. Promise.
It wasn’t clear to me whether or not the UPnP DSF issue was an uncredited actor in your edge-case posting, but it seems that perhaps a couple of other folks thought was. (The other) Chris told me he’d forwarded the issue to the (a?) streamer engineer, and so I’ve been expecting a solution at some point.
Now that I’ve compared the sonic virtues of Qobuz through my old Aries streamer against those of Qobuz Connect through the PMG 512’s internal streamer, I’ve immediately become considerably more anxious for a fix. I undoubtedly need a better-engineered I2S cable than my current one to keep pace with the 512, but the cable-free internal streamer solution sounds so superior across the board that I’ll opt for that, and at no additional cost.
endless spin (USB, I2S etc) upon turning on the unit (from standby or after complete shutdown) - have to do factory reset to get back to functioning
inputs lose sample Rate Display if switching between iñputs have to power down and power up from back to get it back, and only stays if i don’t switch or use Optical (which is my TV audio input)
Strange geometric shapes covering random parts of the display
Unrelated note: still can’t post attachments/pics in forum, AI button sits atop attachment icon regardless (tablet or phone, rotated or not)
The next update, which is coming shortly, should fix the display issues (we’re testing it now) and hopefully clean up a few more. We’re working on the UPnP issue too. On Monday morning, the first, the AI icon will vanish from the forums and you can have your button back.
Yup and I’ll let you know when it’s ready. Peter’s already figured out the how and why and now has to implement and test, test, test. Thanks for pointing out the problem. It helps.
Thanks, Chris. Indeed, I was surprised when a few folks found the AirLens superior to the PMG internal streamer, something that I did not find myself. The first moment I streamed Qobuz through the 512 internal streamer I was hooked. It’s just light years better.
The primary engineer on the streamer is a new up and coming star, Peter Grinwald, and he’s immersed in getting it to sing for everyone. You’ll certainly be hearing more about Peter as time goes on.
