PeterSt Posted March 31, 2019 Share Posted March 31, 2019 5 hours ago, Paul R said: Unless of course, you guys are letting the music player machine go to sleep. If you do that, the iFi will switch to battery power and die off after 10 or so hours. So the answer is, just don't do *that*. Leave the music machine powered on 24x7. Although one could do that, one could also hook up to a USB charging port. They don't switch off when the PC goes to sleep ...

I was just teasing Peter, and not meaning to talk about Phasure in this “low cost DAC” thread! The Pro-Ject is $399 and might not have good input isolation and is PSU sensitive. I haven’t tried to control XXHE with Roon, so I can’t fairly comment. What I am discussing here is plug and play, turn it in and go without “fiddling”, and that the Pro-Ject S2M beats out the iFi Micro in this regard (not taking about SQ here). I dont think thst this is what the majority of Phasure *customers* are looking for for example a USB cable with an approaching infinite number of pluggable configurations I will also say again that XXHE is a terrific bargain, does a terrific job at PCM upsampling and I encourage everyone to try it. I haven’t A/B tested the Pro-Ject S2D against my NOS1a. nor have the plans to.

Come to think of it, the place where I had difficulty — and ultimately gave up — was trying to get HQPlayer to play to my NOS1a — so to better clarify: the Phasure customers understand that it’s a someone unitary environment, which produces outstanding SQ, but works best with the full Phasure stack that @PeterSt has so laboriously optimized over the years.

jabbr Posted March 31, 2019 Share Posted March 31, 2019 8 hours ago, Paul R said: Difference is I am running the uRendu as Roon Ready. Has never failed so far. I suspect it is the software looking for something that causes the drop off the network. The only situation I can think of that causes the iFi to discharge it's battery though, is a loss of power over the USB port. Ah, I see - you have the drop-offs and Jabber has the battery drain. Heres what I mean by “overloading interface”. You switch the iFi from battery power to bus power by turning on and off. Gak. So suppose the power briefly shuts off ... my entire network and servers all come back up in an orderly fashion. But the iFi comes back up as battery powered and will then die despite being plugged into an active USB source ... and when it’s totally dead it seems to need a little fiddling to get it to work again — I’ve seen situations where $ lsusb doesn’t see the iFi so perhaps this is why? In any case I’m seeing what @Jud sees to the point where I tried to upgrade the firmware only to find that the new firmware disables DSD512 in favor of MQA!!!

Hi Paul - Nothing to do with what I want to hear; I'm happy it works in your situation.

Jud Posted March 31, 2019 Share Posted March 31, 2019 As of today, awaiting shipment of a Pro-Ject S2. @Miska, if you would be kind enough: I've read in a couple of places where you mention configuring the DAC properly. There's not using the DAC's own filters and feeding it DSD512. I've seen distortion compensation mentioned, but wasn't sure if that applies if the DAC's filters aren't used. Anything else? I'll be trying it with a battery pack (just a 24,000mAh phone charging battery, 5V/2.1A) and the LPS-1 for power. Running it into my Spectral DMC-12 and controlling volume from there, so will leave the S2's volume control all the way up.

If the DAC is running on battery power, then plugging in a USB cable cannot be allowed to trigger a switch to bus power. Elsewise, in the portable world, you will be draining people's iPhones very quickly. But you should not be seeing that behavior.

Or perhaps don't overload the power/volume knob with a change in battery vs bus powering. I see this as a UI issue. The Pro-ject S2D UI is vastly better. Custom room treatments for headphone users.

When the Pro-Ject arrives, I guess we'll see. I am pretty sure those frustrations are the same as mine - mostly dealing with losing DSD512 in a trade off for MQA processing, and the new filters that are always on. It is quote annoying. Even more so since I cannot get mine to go back to 5.2 software. Ah, the joys of dealing with higher end audio! The power behavior has always been there, and while frustrating, is easily handled the way you and I both did, by just powering the unit continuously. To drop off the net, the software holding exclusive access on the net has to see one of two things; either the USB power drops and the unit depowers, or the interface is not held open and times out. The first is hardware, the second is software in the driver. This is a bugaboo of software that holds exclusive access on the port. Just as an experiment, you might tryin releasing the exclusive access of the port, and see how that affects the stability.
