I've had no problem running through mixtures of both kinds of files for hours on end. In fact, I've never had an issue. If you have the CPU power to do so, try and up-sample to DSD128 (minimum) and see/hear if you like it better (or not). https://positive-feedback.com/audio-discourse/raising-the-sample-rate-of-dsd-is-there-a-sweet-spot/ Link to comment
creativepart Posted November 10, 2018 Share Posted November 10, 2018 Thanks. It seems when I set this up DSD64 was the only option. But I just checked and it was changable to DAD128. Hopefully, my aging iMac can handle it.

arcman Posted November 10, 2018 Share Posted November 10, 2018 My S2 stays on 24 -7. I have long usb cable down to my main studio computer (which stays on 24/7). Plus, I still have wall wart plugged in and hooked to smart circuit to come on with my pre-amp. I have never had an issue with the S2 with power outages or anything. As a former manufacturing manager for many years, if expectations are not there from the management level, corners can get cut when there is high volume demand that puts pressure on the manufacturing process. In the auto industry, high demand = overtime work which does not guarantee the same workers are doing the same tasks that they were doing during normal business week. The plant must have strict certification processes that allow flexibility with assemblers. I'm not saying this is the case here...but its a normal manufacturing issue that the great companies (Toyota, Honda, etc) have mastered. Link to comment
Mark Dirac Posted January 14, 2019 Share Posted January 14, 2019 My PC updated to Windows 1809 today and my S2D stopped working. It was a head-scratching waste of half an hour to get it going again. When I first plugged in the S2D (into USB) Windows reported it was "setting up a new device" and that "is now working". But S2D did not appear in the sound options. The only place it appeared was in the settings page for Devices, where I was informed "driver not found". No plugging/unplugging and restarting would fix. In device manager, I selected "update driver" and pointed device manager to search my hard drive and it found a driver & installed it. Now working. I would be interested if anyone could tell me what's going on, why the 1809 upgrade would cause this one device's driver to go missing, even though Windows "set stuff up" when I first plugged the S2D in. (I hate Microsoft.) Thanks. Link to comment
left channel Posted January 15, 2019 Share Posted January 15, 2019 @Mark Dirac that didn't happen to me with the 1809 update, though it's not at all surprising after decades of the same behavior. Still, I have to wonder if this is yet another example of poor testing at Pro-Ject. Over on pinkfishmedia it's been reported that an S2D stopped working with someone's iPad after the latest iOS update. Mark Dirac 1 Everyone wants to date my avatar. Link to comment
Popular Post Miska Posted January 15, 2019 Popular Post Share Posted January 15, 2019 I guess I'm lucky Windows is failing to install 1803 on the machine where I use the Pro-Ject DAC at the moment. Even Microsoft was unable to install that update after half a day of trying... They said they would escalate the issue, but never heard back since (several months ago). So far I have three machines converted from Windows to Linux because Windows screwed up itself all on it's own... buonassi, Mark Dirac and left channel 3 Signalyst - Developer of HQPlayer Pulse & Fidelity - Software Defined Amplifiers Link to comment

I hope all the advertising of the S2D Pro-Ject is doing on this site is an indication that they've also invested some money in maintaining it. The release of this new driver may indicate they are indeed doing so. My guess is that Thesycon is the contractor they've retained to take over from John Westlake on driver and firmware development. Based on their website, that is their specialty. As for the three components, the control panel apparently comes with the driver package and communicates with the driver and the firmware, to offer control and monitoring of what the PC sends and what the device does with it.

fgribas Posted January 15, 2019 Share Posted January 15, 2019 "Pro-Ject Audio Control Panel" is a part of the driver. Thesycon is a company that makes the driver for Pro-Ject any many other DACs based on XMOS chip. For the firmware I'm not sure, but I think is also made by Thesycon. Mark Dirac 1 Link to comment

Pro-Ject is aware of the need for a new firmware. I've been talking with their support about firmware and drivers. Hopefully it will be released soon. Thesycon won't take over the product, unfortunately. Not for free. As far as I know, the manufacturer (Pro-Ject) pays Thesycon to develop new drivers. By looking at the 3 versions of the driver we have so far (looking at the inf files, control panel etc of each driver), it seems that all of them were made by Thesycon. Link to comment

Thesycon worked in close consultation with John on the drivers then. Interesting. Well, according to their website they also do firmware, and we can only hope that one or the other will produce a firmware update for this device, and for the other DACs in the S2 line (which still contain bugs that were fixed in the last firmware update for the S2D). fgribas 1 Everyone wants to date my avatar.

Miska Posted January 16, 2019 Share Posted January 16, 2019 So far, all driver's I remember seeing shipped with XMOS-based devices have been Thesycon ones. Lot of devices out there that use XMOS chips have either XMOS' or Thesycon's USB vendor id. Only few manufacturers get their own USB vendor id. So you pretty much also know where the firmware was sourced from. Signalyst - Developer of HQPlayer Pulse & Fidelity - Software Defined Amplifiers Link to comment

He also responded to us about driver / control panel changes in a way that sounded like ownership, but apparently he was working with Thesycon on those. John is no longer associated with Pro-Ject, but a few months ago he promised to produce one final firmware bug fix update — on his own time, for free — just for completeness. He also said he then wanted to offer an optional inexpensive firmware upgrade, to realize his full vision for this design. However, since then he's seemed fully occupied with his MDAC project, and hasn't responded to further queries nor made any statements on this topic. Everyone wants to date my avatar. Link to comment

Mark Dirac Posted January 21, 2019 Share Posted January 21, 2019 I have given up with the complexities and ambiguities of MQA and Tidal Masters, and have moved to Qobuz. Thanks to left channel for the gentle persuasion. But I am surprised to see such a baffling set of "audio output" options, and can find no explanation or FAQ answer. My selected output "Pro-Ject Box ASIO Driver" does not appear anywhere in Windows 10, specifically nowhere in the Windows 10 Sound Settings. Is it the case that Qobuz is bypassing Windows's sound stuff straight to the Pro-Ject driver somehow, in a way which Tidal does not? Can anyone enlighten me please? Left channel? Link to comment

That Pro-Ject ASIO driver and many others are always available in your system. If you look instead at the list available via Account icon > Music Playing > Listening preferences, you'll find that one and other unfamiliar choices listed there, and other player apps often list even more. The pop-up menu you've opened in the screen shot above is an attempt at simplification similar to what the main Windows Control Panels and the Tidal app do: hide everything except connected hardware "Speakers". Something weird about the Pro-Ject ASIO driver causes the Qobuz app to display it there too, probably because it is the manufacturer's priority driver for that device. It works, but WASAPI is a newer driver standard and works great with the S2D too. Try Exclusive Mode, just like in Tidal. Oh, and welcome to the Light Side!

fgribas Posted January 22, 2019 Share Posted January 22, 2019 It's just a matter that Tidal app doesn't support ASIO output, only WASAPI. This is the main reason I use Roon, it supports output to ASIO drivers. WASAPI (wth Exclusive Mode) and ASIO are both bit-perfect. But ASIO sounds better. Not every bit-perfect chain sounds the same. ASIO is better than WASAPI (many will disagree, many will say "bit-perfect is always the same" but that's not true). Kernel Streaming sounds even better than ASIO, but there's a compromise with stability and compatibility. Almost no app supports KS. Well, to use Tidal with ASIO you need another player that supports Tidal and ASIO output. Roon is great, but expansive as hell. You can use the default Tidal Windows app with the ASIO4ALL app: it's a virtual driver routes a WASAPI output to an ASIO driver. I used this chain before buying Roon. Mark Dirac 1 Link to comment

Good to know we have a cheap alternative to Roon to get Tidal + ASIO. 😊 Speaking of which, yesterday Roon released a new version that's integrates with Qobuz. So I started my trial account. And OMG! Their HiRes releases are awesome! Thanks for the tip @left channel My Tidal account is in serious danger. Now my chain is: Roon playing Qobuz -> Upsample + EQ -> ASIO -> JPLAY -> Kernel Streaming-> Pro-Ject S2D -> Shure SE846 Sometimes I prefer upsampling in Roon, sometimes in HQPlayer.

RicaNeaga Posted February 16, 2019 Share Posted February 16, 2019 Hello! Just bought this DAC, and I've read several posts on this topic regarding power supply. Can you please recommend the best choice for a power supply? To be more specific, I want to connect it to my PC via the USB port (for Tidal & MQA), however I found this in the user guide: Quote 2. USB input is in use: Unit can be powered directly from computer via USB input. In this case is highly recommended to disconnect Power 5V DC cable from the unit - power disturbances from two power supplies could affect sound performance So what choices do I have? Is really an external power supply out of the question when using the USB port for PC connectivity? I've seen many thinking of buying ''chinese linear power supply'' - are these better than a iFi Audio iPower 5v and can these be used concurrently with a PC USB connection? Can you recommend some specific linear power supply that are below a 100 euro price limit? Thank you in advance Link to comment
