As always, you insights are valued and valuable.
My current stereo is
18 years old (
), I haven't turned it off in 5 years or so to avoid having to deal with a blown capacitor, It's been years since I've listened to a station other than WQXR-FM classical, I haven't used any of its other functionality in years (but I want to maintain turntable functionality), and I doubt that I'll be looking for a new one before this one dies, but against that day I did some cursory research and found that AirPlay and wi-fi capability are really scarce; Bluetooth is what's mostly available, but from the little I've read, it's subject to proximity limitations, would require a $30 app to make it work with my MBP, and while not subject to dropouts, provides lesser "reception" than wi-fi.
Bottom line... $50 refurbed (v $100 new) AirPort Express units came up in the Apple Store, and I bought one. (I'll just have to maintain Airport Utility functionality in one way or another
if when Apple discontinues it.)
