I haven't used the Nano in some time...primarily because it is more fiddley. But it does have a nice warm sound. I'll probably be using the Nano this week.

The Compacts are hard to beat. Easy to set up, light and no EQ fiddling. Coverage is excellent.

I've been using a Bose L1 in some form or other for close to 10 years now. They really are hard to beat.
