Hi @Gimlet. I downloaded a trial of Virtuoso and wanted to test it out. It took me some time the get the audio routing from Roon to Virtuoso to work on Windows. I didn’t succeed with JackAudio but it finally worked with VB-Cable.
Now I want to test it out with something else than Qobuz’ classical 5.1 tracks. Can you recommend some good pop/rock multichannal recordings for demoing?
I see that they have a Black Friday sale this year again. So now is a very good time to buy 
Hi. Most of my multichannel collection is ripped classical SACDs or old quad recordings from the 1970s. I have picked up a few classic rock recordings - notably Dark Side of the Moon which sounds amazing in multo-channel. Also I have a Porcupine Tree album which sounds great.
But if you go onto the web (eg Head-fi’s Smyth Realiser section) you will get better recommendations from the serious rock and surround fans. Enjoy!
Thank you for the suggestions

Update - I have spent the last few months testing the Supperware headtracker and the included Bridgehead software - cost about £80 in the UK. Overall very positive feedback and “out of the head” realism (when used with APL Virtuoso v.2 https://apl-hud.com/product/virtuoso/) although the magnetic tracking isn’t as good as the optical tracking on my Smyth Realiser. However, it gives a fairly convincing rendition of anything from 2.0 to 7.1 channels in a home audio or cinema room with simulated Genelec or Spendor loudspeakers. Also works well with Netflix playing 5.1 movies using the Netflix 1080p extension for Chrome.
+1 easiest way to keep up to date with past and upcoming multichannel releases IMO
Also worth mentioning, some of the older quad mixes, particularly from the 70s are AWESOME, and for albums that have ended up being remixed into 5.1+ , sometimes an interesting counterpoint to those newer mixes.
Big big multichannel fan, I’m so glad it hasn’t died. There were a few dark years but I honestly think, BD-A combined with what Steven Wilson started doing really revitalized the interest in multichannel.
Yes it’s great to see more interest in multichannel and immersive mixes. As well as talented people like Steven Wilson, I think this may also be driven by better immersive headphone technology, as well as, of course, Dolby Atmos. I visited the Dolby studios in SF a few years ago, and was lucky enough to be given a tour by one of the lead Atmos developers (the husband of a colleague).
Alongside the amazing sound quality, I remember being impressed by the 16 and 24 channel mixing studios (see ATC studio pic below) and multiple Smyth Realisers - which eventually inspired me to get my own Realiser. I should also mention the improvements in upmixing technology which has really enhanced my enjoyment of stereo. Listening to stereo classical and opera upmixed to 16 channel surround using Auro 3D is a whole new experience. No weird surround effects - it’s just far more immersive than normal stereo.
Gorgeous studio.
I’m not a fan of upmixing on music but I do dabble in my own stuff. A Steven Wilson interview actually helped me realize that I was on the right track with the approach I had been taking (weirdly mirrored what I do).
Basically, I mess around with material where I have access to the original multitrack recordings / sessions, I start by ‘rebuilding’ the mix, close to the original in stereo, and then from there I build it out into 5.1.
OK so I got the Virtuoso program and I’m learning as I go along. If you don’t mind some newbie questions I have some
After some reading I found out that it does not seem possible to decode Atmos on a windows PC without the Dolby Reference Player which they only sell to companies. I think 5.1 or 7.1 sounds good through Virtuoso but how much am I missing when compared to a fully decoded Atmos track played through Virtuoso?
I can rip an Atmos blu-ray and play it back as 5.1 or 7.1. What setting do you use in Virtuoso for such files ITU-R or the Dolby Atmos settings?
If I rip to MKV Roon can’t play the file. What player do you use to play multichannel MKV’s? I used good old JRiver but it sorts MKV files under video making it a bit messy. Are there any good alternatives?
And finaly I’m thinking about getting a custom HRTF made. I know of Genelec’s Aural id. Are there any other good options?
I am mainly a Mac and ROCK user, so apologies in advance if my Windows knowledge is limited.
Dolby Atmos - you are 100% correct that Virtuoso doesn’t include an Atmos decoder. To my knowledge, the only headphone processor that includes Atmos, DTS-X and Auro decoding is the Smyth A16 Realiser (which provides up to 24 virtual speaker channels). Having compared both the Smyth and Virtuoso on stereo, 5.1 and 7.1 music and movies, there is a significant difference especially in bass quality and precision of speaker location, but Virtuoso is still great value for what it can do.
However, I haven’t personally found Atmos music (from Apple Music) to be super impressive - it seems to be lossy and/or upmixed. Movies are a very different matter, as Atmos can transform your entire experience. I have also played ripped Atmos blu-ray music through Virtuoso, using the 7.1 SMPTE layout (which has the classic F C R speaker location) with good results. The Virtuoso manual gives a lot more detail on alternate speaker layouts so you can experiment.
MKV - I have only played MKV movies, not music. So I can’t advise on this. I have transformed all my multi-channel music ripped from SACDs into FLAC files, and these play fine, alongside the limited multichannel FLAC streams from Qobuz.
HRTF - I believe that the Genelec HRTF costs around £1000, just for the measurements. If you are prepared to spend that kind of money, you could consider buying the Smyth A16 Realiser ($4,000) rather than Virtuoso, as it has full HRTF personalisation and room/speaker measurement capabilities, and is the go-to headphone virtualisation tool at many studios, including Dolby themselves. I also own an A16 Realiser but use Virtuoso when travelling. It’s a big investment, so check the Head-Fi thread https://www.head-fi.org/threads/smyth-research-realiser-a16.807459/ if you are interested.
Virtuoso works best with a headtracker, and preferably some ability to modify the HRTF response for individual ears. Most people recommend the £80 Supperware tracker (which I use), but then you are restricted to the 5 standard HRTF options in Virtuoso. Another option is Earfish https://www.earfish.eu which used to enable you to maker a custom HRTF. However, Earfish now seems to have been restricted to academic research users. The third alternative is Waves NX https://www.waves.com/hardware/nx-head-tracker which also has some HRTF personalisation options.
Hope this helps. Good luck!
Thank you for the advice.
I think the Genelec HRTF pricing is down to 375€ now. The Smyth A16 Realiser is sadly out of my budget range
I will check out the headtrackers
