Hmm, I'm of two minds about this

On the one hand it's simply a ridiculous increase and pretty indefensible as a jump. Especially given that it doesn't really offer much you can't do for free with something like jellyfin

On the other hand at least they still offer a lifetime sub, crazy expensive yes, but the option is still technically there for someone who wants to use the software without subscription. Plenty of companies have gone down the sub only road, and I think we should give at least a bit of credit for them not doing the same, even though they'd clearly like to

I know audiophiles are a bit of an outlier in general, but Roon lifetime is even more IIRC!
