OK, let me try.
Let's compare with JRiver which costs $60 per platform or $80 for a license covering all the platforms on which they operate. Their policy is that you may use a single license on “all your computers, within reason”. A major version update typically costs about $40 but it's important to understand that, should you choose
not to upgrade, you retain the right to continue to use your existing version indefinitely. I know several audio-only users who are entirely happy with a version several years old because, quite frankly, JRiver cracked audio playback a
long time ago and there remains little to be done.
Comparing with the cheapest Roon option, $10/month. That's $120 per annum but my understanding is that Roon operates entirely on the 'rental' model; that is, the moment you choose to stop paying, you loose the right to use the software. There was one thing in their self-promotion that truly made me shudder.
“Discovery algorithms being trained by 20 million listens every month by the most capable music enthusiasts”. Now I truly don't know what Roon are doing here (does anybody?) but if there are aspects to computer audio playback that are adjustable by the popular vote then Roon truly have discovered something unique
Roon appear to be truly immersed in the MQA legend and clearly have a good business arrangement with like-minded hardware companies. Roon is clearly the more expensive product and, quite frankly, I'm finding it a bit tricky to comprehend what I'm getting for the extra outlay but, looking at their web site, I get the feeling that they are very much trying to market Roon as a “lifestyle” product, comparable in price to some of the "massive rip off" priced hardware they are seen to be in bed with. It is, in fact, audio playback software with a few bells & whistles.
