Re: SOP for Logitech, I am afraid
I have an old SB3 and a Touch. The SB3 is in my study and doesn't get much use so hopefully it'll be fine. the Touch gets a lot of use but shows no signs of trouble. I recently replaced my receiver so now I could use that instead. Unfortunately the receiver has a rubbishy one line display so I'd have to switch the TV on to get a decent interface which seems silly just to listen to music.
I also don't know if the receiver's implementation supports random shuffle by album. A lot of them don't :(
