+1 for the Innuos Zenith Mk 3! Works great, sounds great & the app is logical, easy to use on an iPad .I know this will stir up a lot of reactions but I pair it w/ the Border Patrol DAC for a combo of about $6.5K. For a 50 year turntable guy, who made the plunge into streaming, the combo sounded better to me than many more expensive & highly touted ones.
For myself & assuming a sound system doesn’t do any egregiously wrong, listener fatigue is the real test. Do I want to keep listening & enjoying the music or do I feel the need to change it or turn it off altogether? Along with Qobuz & my sstreaming setup, I have spent many late nights enjoying a virtually unlimited library of fun!
