left channel Posted June 4, 2019 Share Posted June 4, 2019 Clearly the preferred solution in this thread is not MQB. It's Qobuz! 🙂 Blaming everything on MQA Ltd. is convenient for Pro-Ject, but then how have other small companies managed to create more robust solutions? Perhaps through better testing and better developer management? Purists may not like Mytek's solution, but the fact remains that when several of us tested one of the worst possible situations (an unexpected upsampled monstrosity of an MQA CD on Qobuz), a Mytek DAC succeeded in locking on or falling back to 24/48 and remaining stable, while the Pro-Ject S2D failed.

Wish MQA was a seamless experience at this point. After pursuing Pro-Ject on social media I received an official response: Also after much experimenting with Roon and Audirvana, I have come to the conclusion that Audirvana sounds best during the MQA dropout. Instead of having the sound dropout completely like Roon or the Tidal player it introduces a little bit of audible static while it looses decoding. I will be utilizing the MQB workaround while patiently waiting for the next firmware update. Pro-jects response prevented me from selling this DAC right away. I asked if the update is scheduled for release this year and will post the response if any. Just another reason to avoid MQA. Stick with straight Redbook or hi res.

Pure MQA (1st unfold + MQA own filter) can sound better than redbook, or the same, or even worse. Qobuz and every other real hi-res source is better than MQA, no doubt about it. I currently have Tidal and Qobuz subscription, both used on Roon. And I'm very happy with it and my S2D. Everyone will have his or her own impressions in this regard. I listened to MQA doing the first unfold and upsampling in Audirvana, and I mostly preferred not only hi res but regular Redbook to the MQA versions. There were exceptions, but they were obviously different masters (instruments in different locations, for example). That's of course only my own experience.

Perhaps through better testing and better developer management? The "more robust" solution is to feed everything through MQA process, also non-MQA content and let it apply MQA's static upsampling filter to all that data? Which results in poor performance. And then the "more robust" option is left up to user to turn of and off the MQA altogether manually if they wish to avoid MQA from screwing up also non-MQA PCM content? 4 hours ago, left channel said: Purists may not like Mytek's solution, but the fact remains that when several of us tested one of the worst possible situations (an unexpected upsampled monstrosity of an MQA CD on Qobuz), a Mytek DAC succeeded in locking on or falling back to 24/48 and remaining stable, while the Pro-Ject S2D failed. Since MQA code has been found to be quite buggy, different companies may also have different versions of the MQA code, some more willing to issue regular firmware updates to deal with such updates too. ALWAYS turn off MQA support from Mytek if you don't want your regular PCM content screwed up by it. Of course best way to avoid such problems with both DACs is just keep sending them always DSD and you won't have such problems.

Popular Post left channel Posted June 4, 2019 Popular Post Share Posted June 4, 2019 Thanks @Miska. Pro-Ject is not known for regular firmware updates, that's certain. Anyway as agreed above, the best solution to these problems is... Qobuz! 🙂 Jud and Mark Dirac 2 Everyone wants to date my avatar. Link to comment

The MQB solution to this issue isn’t any less of the “official” MQA experience btw... Instead of DAC doing both 1st unfold + “rendering”, Audirvana will do the 1st unfold and the DAC will do just the “rendering” part. Jumpwire 1 Link to comment
Mike Rubin Posted June 5, 2019 Share Posted June 5, 2019 Allow me to ask something more basic than about MQA unfolding: If I don't care about Qobuz, Tidal, Roon or MQA and just stream FLAC and DSD files from a NAS to a microRendu to the DAC, is this a good product for the money?

sebassie Posted July 1, 2019 Share Posted July 1, 2019 After using the Pre Box S2 Digital for 6 months (24/7) the display shows problems. I use USB and have volume up (0 dB). All information is shown in 'white'. Two days ago this changed into 'brown'. When turning the volume knob ccw the digits shown are 'white', but the 0 dB and the USB icon in 'brown' stays. It looks as if the screen burnt in or something like that. Has anyone similar experience? Link to comment

Mike Rubin Posted July 3, 2019 Share Posted July 3, 2019 Heard this and was impressed greatly, especially with the "heft" of the the delivery. One question, though: not a huge deal, but does this DAC support native DSD or are those impressive DSD specs for DoP?
