Others have ported SBT to the RPi so it should be relatively simple to add to the CM3 (RPi3) based MDAC2 streamer.

The User controls of the MDAC2+ (MDAC2 with upgraded front panel) are on a separate touch panel and interfaced directly to the MDAC2 MCU so will operate independent of what software is installed on the CM3 - however we rely on the UI on the display panel to indicate volume level and input source etc. so there will need to be a simply UI addition to any SBT software port to indicate the MDAC2+ "front panel interface".

Unfortunately for those of us who listen to a lot of classical music, Roon's supposed ability to provide enriched and accurate metadata (and hence searching capacity) doesn't actually work.

I don't have Roon as I can't justify the cost. Even Tidal admit it has features better than Tidal and are trying to emulate it's embedded links.

These embedded links are what really distinguish it over other music players/streamers...these go deep with Roon and don't seem to slow the program down on most computers (it's got some good/fast/efficient search code or database architecture). Apparently even engineers and session player on a piece of music are cross linked so you can find everything that they have worked on. Band members and related artists, labels, etc.etc. links goes without saying.
Yes that is a good introduction to how UI works, but since this was recorded the Roon team has added more functionality and that makes the software even better value.
  • Upsample to DSD512 / PCM 768Khz
  • DSP functions Parametric EQ, Crossfeed
  • Roon Optimized Core Kit (ROCK) which is a OS that makes it easy to turn a NUC into a Music Server which does all the heavy lifting like LMS
All processing is done on the Server the RoonBridge is only receiving DCP, DoP and Native DSD and are therefore very light weight on the CPU.

The great thing about Roon is that it lets the DIY people build the same things for free that the commercial brands build into their products.

When did you last check this? They have recently made improvements and will continue in the future. They really do listen and are very active on their forum.

Luckily I do not listen to a lot of classical.

Nothings perfect but Roon is close maybe not for classical but that not my thing anyway.

John,
There is actually a solution called RuneAudio it is very similar to Volumio and is also MPD based.

I know you meant Roon when you said Rune, but I simply could not get myself to correct you because I enjoyed the name dropping to much

Currently running a free trial. I wasn't hoping for much, and it hasn't delivered. Basically browsing classical music using Roon's metadata is impossible, because there's no consistency in how the fields are used (who counts as an 'artist'?) or how the metadata is entered (e.g. spelling).

The problem gets worse when you try to integrate your local library with a streaming service, because your own library may be beautifully organized, with all the fields used consistently and all the spelling normalized (Rachmaninov or Rachmaninoff?), but Tidal's metadata is all over the place. So your browsing menus get populated with all sorts of stuff you don't want there and stuff that's been inaccurately entered.

Classical music metadata is far more complex than for pop/rock/jazz etc, for a number of reasons that I won't bore people with. There is really only one way to deal with classical music metadata, and that's to edit it yourself according to your own (hopefully rational) system.

It is only nice to have a UI indicator for SBT or Roon but not necessary.
You only need to be able to select the streamer as a source then it will play whatever is send to ALSA output be it Volumios MPD, squeezelite, RoonBridge etc.

Yes it will be possible to make better integration to the UI but not essential. Roon have released a API so the community can make their own integrations. I have just ordered a 7" touch screen for my RPI (the official crap one) to try it out.

"Upsample to DSD512 " does mean it can convert PCM to DSD? If so, I'd be interested to hear from John whether he thinks that it would be worth doing when playing via the MDAC2. ( I suspect John will say no, its DSD played natively that brings benefits, but maybe I'll be surprised. John?)

Yes it can convert PCM to DSD and even upsample DSD64 to DSD512 and apply DSP functions as well if you want.
I also upsamples mp3 raidio streams to DSD if that is what you want

I am also a bit sceptical about the benefits of upsampling, but there is lots of people that claims it makes a difference with their DAC so I will not rule it out.

I have been arguing for years that we need a European Metadata Regulation enforcing, on pain of savage penalities, the consistent use of composer, conductor, band, identified individual artists (with discipline separately recorded in a sub-field ), choir(s), work, location, recording date, recording release, original label, re-release label. And of course spelling.
I imagine that it probably would have run into immediate and intractable disputes between the English, French and Germans over Handel.

I cannot say when I can get you a Pro-ject DAC - but I can repair your MDAC for you.

He is still a German composer

You have the choice in roon to use either their metadata or your own carefully manicured tagging
With roon and tidal , I have not bought any new music for almost 2 years.. I used to buy at least 50 quid a month.. roon and tidal are less than 1/2 that..
SQ is superb and their DSP engine is amazing .. you even get a convolution engine for complex time and freq correction
I bought a lifetime roon membership at $300 on a "special" , worth every cent and it was mickey mouse money compared to my system cost
FWIW I thought the M-dac was a very fine dac .. until mine broke
Nowdays , for me , with devialets .. a stand alone dac is moot
