kissov Posted January 5, 2017 Share Posted January 5, 2017 Will the microRendu pass MQA encoded music? Tidal now has a "Master" section with about 100 MQA encoded albums, sound great, tighter base, cleaner, wide and deep sound stage. Right now. iMac-- Tidal--Uptone USB regen--Meridian Explorer 2-- Schiit Jotunheim--balanced HiFiMan mod "X" Link to comment
gahabana Posted January 5, 2017 Share Posted January 5, 2017 No reason why it should not. Assuming you use LMS tidal plugin or Roon server wth Tidal. Only if you use NAA then it will change datastream unless there is capability for NAA to recognise MQA and then not dobthe usual upslampling/filters etc. Sent from my iPhone using Tapatalk Link to comment
kblundy Posted January 6, 2017 Share Posted January 6, 2017 A bigger question - is there a plan to do the MQA decoding in the microRendu so that those of us without MQA DACs (nearly everyone) will be able to benefit. Is this possible / practical? Sent from my iPad using Tapatalk Link to comment
vortecjr Posted January 6, 2017 Share Posted January 6, 2017 "Master Quality" Audio sort of reminds me of iTunes saying "CD Quality" downloads:) Has anyone compared MQA to up sampling to the same MQA rate or up sampling to DSD? Anyway, MQA streaming is supported because we support FLAC. MQA decoding is not supported. The best place IMO to support MQA decoding is at the server or DAC allowing us to do what we do best between the two.

MQA has clearly decided, for business reasons - also clearly, driven by Tidal - to license a SW decoder that does a partial unfold of their origami, to double the container sample rate. This tops out at 88.2 or 96, and is NOT full MQA decoding in SW. However, it IS a step up in SQ, and enables access to high-er resolution than was ever possible before with Tidal. This has been licensed by Tidal, Audirvana, not sure who else. Having invested $$$ in a non-MQA DAC I really like, I take the opposite view - you guys should license this, because a large fraction of your customers are like me. Now, whether it makes business sense, is it cost-effective, will it even run on your HW - these are your decisions. And I respect your right to make them. But as someone who has been eyeing an mR for a while, MQA on Tidal has changed my parameters. My next NAA/endpoint/renderer needs to do MQA decoding. Not criticizing or judging - just providing customer input. My Audio Setup Link to comment

Only if you use NAA then it will change datastream unless there is capability for NAA to recognise MQA and then not dobthe usual upslampling/filters etc. Sent from my iPhone using Tapatalk HQPlayer can be set to not upsample at all. This should work. However, there's no way to not upsample MQA but upsample everything else. If playing an MQA file directly on HQP, HQP can recognize this by metadata and Miska could add a feature to leave the file untouched in such case. But if streamed by Roon, the metadata is lost and your only option is to never upsample. just thought of one workaround - not great but better than fiddling with HQP settings all the time: when you want to play an MQA file, switch the microRendu to RoonReady and set a speaker in Roon to that. Then play Roon to the RoonReady mR. You must defeat volume to not change the file obviously. This is the slickest I can think of. If controlling from an iPad, you can put a shortcut on your apps to the mR app switch.

ping801 Posted January 8, 2017 Share Posted January 8, 2017 I use Tidal desktop to create a playlist by adding some of the albums under Master listing. Then, played the same playlist via Tidal desktop app to make sure they are recognized as MQA encoded. Then, I swapped out the dirnect USB connection with microRendu and played the same playlist via Linn Kazoo. But, now MQA is not detected. Also, I played the downloaded MQA files from 2L using JRiver with output format set Original for the microRendu. Those files are not not recognized as MQA encoded either. They are recognized as MQA encoded once I swap out microRendu with direct USB connection to MyTeK Brooklyn. I am not sure what might cause this discrepancy. It might be as simple as configuration. But, please help. Thanks and regards Link to comment

The only thing I could say is - do your own research. The facts do not support that conclusion. This would depend on how you define DRM. MQA encoded files deliver below CD quality who played back without MQA decoding, and MQA decoding is closed source requiring a licensed decoder only available in certain products. Because it is closed source, if you purchase MQA files, and you do not have an MQA decoder, you cannot access the content (excepting with sound quality loss). Sounds like DRM to me...

I think it would not be a good idea to buy MQA files. MQA is a fig leaf for the music industry. It gives them a way to offer, thru streaming, something like hi-res and do it using something like DRM. They can say that they are offering listeners a true hi-res experience without exposing the real high resolution master file to the stream of commerce where it would certainly be abused. They learned their lesson after the file sharing debacle and will not make that mistake again. They will never offer a real hi-res file of any commercially viable music. Maybe classical music recorded in an old church in Norway but not any artist that they can count on to sell in large numbers. Link to comment

comedus06 Posted January 9, 2017 Share Posted January 9, 2017 It appears to me that there are two things in parallel going on here: - Hi-rez STREAMING - this is a non-existent or rapidly declining problem (at least where most of the revenue is generated US, Western Europe, etc). Netflix, Hulu, Amazon, the Cable/Internet providers are already delivering much higher bandwidth content without piracy/abuse so I don't think that bandwidth/piracy while STREAMING are the big concerns for studios. MQA's value add in this context seems to be mainly the "origami" stuff i.e. folding/unfolding. - Hi-rez DOWNLOADS; this is what I think studios are concerned about - giving up the "crown jewels" as someone from MQA had described it. Once they make a high quality master in hi-rez available for download, they have nothing more to peddle later. For this, MQA could help (not currently but after widespread adoption if that ever happens) by adding DRM/copy protection. - For consumers, MQA's value add seems to be about de-smearing of the original ADC and downstream DAC. No clear A/B of this exists or where an improvement/degradation is perceived, we can't tell whether it's because of a new master or because of the MQA coding/de-coding. Mansr's data from another thread, however, clearly shows something amiss about "improved" fidelity. Happy to be corrected if you have other thoughts about the motivation in this for the studios (though it's only Warner right now). What!

As long as the service exists, they'll provide software to decode it. If the service goes away, I'll no longer be paying so nothing will be lost. The trouble with DRM on downloads is that if the provider vanishes, you're left with unplayable content even though you've paid for it. This has happened several times already. Link to comment
comedus06 Posted January 9, 2017 Share Posted January 9, 2017 You're absolutely right. I hope that the other streaming guys forget about MQA considering they have successful streaming models (Netflix, etc) that prove it can be done in a commercially feasible and an abuse free (almost) way. The studios can keep doing MQA for hi-res downloads if they want, especially if it prompts them to release better masters or re-master for streaming purposes than they otherwise would have; no one will buy the closed-format MQA stuff and it'll eventually die but leave behind a library of better masters in hi-res for streaming.

There are no options to set Linn Kazoo or Openhome renderer to behave differently on MQA stream. What might be misconfigured to cause the MQA stream not to be detected in Configuration 1? Any help will be much appreciated.

I created a Master playlist in Tidal PC desktop app and then I played it by streaming it from bubbleupnp to Jplaystreamer on my PC connected via USB to my brooklyn dac but it only shows as a flac 16bit 44.1khz file. I sent an email to bubbleupnp developers to ask them about MQA support but no answer till now Sent from my iPhone using Computer Audiophile Link to comment
