The actual amp, I’m very pleased with.
Having heard the Gato kit in the past I was pretty confident of how it would turn out.
My household is very much wedded to Sonos and Spotify, having bought into each system shortly after it came out. Sorry, but I’ve never tried Tidal.
The DAC in the Gato is, err, adequate. I’m not someone who can / claims that he can hear big differences between DACs. I just view the Sonos as being a means of delivering 44.1 to the amp, while having a good UI and being pretty reliable. The amp itself makes far more difference to the sound than a DAC ever would. Then again the amp’s contribution is dwarfed by that of the speakers and/or room.
The Sonos / Spotify integration is OK, although I prefer the native interface on PCs and phones.
