hi @bwguy my preamp is pure analog, so no DSP processing. Right now, I'm just going to let it run continuously for another week and see how it goes. Like I said earlier, SQ wise, I like everything about the T2, except I wish the bass is a little more pronounced.
As with the app, it's actually not so bad when it is WORKING. Unfortunately, it seems very unstable. It quits (or crashes) all the time. Sometimes when I restart the app, it won't connect properly, and I can't even control the playlist. I really don't like the fact that the app is the only option to use this unit. With the Cambridge Audio I have, I only use the app to construct the playlist that I want to listen to, and even this step I can do it without the app. I can do everything else via infrared remote, like start, stop, skip, and rewind, etc.
If my experience with the app doesn't improve, it might be another show stopper for me to keep this unit.
