Hi, Ed,
I’ve had my B2 for a few years now. It has been wonderful for me. I had no difficulty setting it up, ripping my collection, which wasn’t very much larger than yours then, and playing. It’s so easy now with the Web interface to choose and play.
I had a small query which is why I joined the forum. I stayed because I’m fascinated by the expertise of some here. I’ve learnt how to set up my PC as NAS, and do some things because of that, like listening to my music anywhere in the house on my tablets using VLC, and uploading music bought from Amazon.. I’ve connected Sonos speakers too. I asked a couple of questions here, but nothing that was a huge problem. I think many of the problems here are to do with the wifi signal not being so good, (though mine at first wasn’t quite as good as it’s recommended and I was fine).
BUT mainly I rip on the B2, and listen on its speakers. If you want to do nothing more complicated than that you should be absolutely fine.
