Thanks for the input, Dan. My needs go beyond the analog tuner I already have. I'd like to be able to switch stations from my Control 4 based app on the iPad.
Analogs don't seem to do that very well.
I don't route the Sonos signal through my MR-77 or C28, which are used for local FM only at this time.
I do love my MR-77 for that pure sweet sound, though.
