I own the Innuos Zenith 3 and can tell you that Sense sounds far better than Roon on an Innuos player. Roon sounds flat and dull compared to Sense. Sense is more open sounding with better inner detail retrieval and improved realism. Roon’s bass is thicker and has less articulation compared to Sense.
The Sense program is miles ahead of where it was when it was first introduced. I must say Roon is a slightly better interface in terms of available artist info, lyrics, navigation and such. It just is. Roon radio is a very nice feature not offered in Sense. It plays artists similar to the ones you know and love and is a great way to learn of artists you may come to really enjoy. As much as I like the Roon interface I simply can no longer listen to it after hearing Sense! This coming from a Roon lifetime member 😬
I highly recommend getting the Network Acoustics Muon filter package with your streamer. It really improves the streaming experience by improving the realism and your connection to the music. It peels away noise that disrupts engagement. Wonderful piece with a trial period.
