I haven’t tried the new Titan model, but comparing the Roon Nucleus vs the Mosiac app I think the Mosiac app is slightly better. Quieter, with a more natural tone. However, I have closed the gap a bit by using an Innuous switch feeding the nucleus and Rossini. For me the convenience/user interface of Roon far outweigh the small sonic gains that Mosaic provides and so I only occasionally use Mosiac to play music…mostly just to compare to Roon and to make sure my Roon setup is not wildly out of whack.
