Roon Nucleus Titan is not for everyone. Neither are $100,000 music systems and 800,000 music tracks. If you don’t want a Roon Nucleus Titan, don’t buy one. I’m sure there are some here who will jump on it just because it’s expensive, and will proudly display it in a conspicuous place. Roon customers are a diverse bunch.
That said, it’s not something I would ever buy unless I had a huge library and the Nucleus Titan was the only server that could deal with it effectively.
