Oh, I love my Squeezebox Boom. Been wanting an all-in-one Squeezebox since forever, so when it was announced I ordered one straight away and got one from probably the first batch in the UK.

Its one of those things, just as Andy says - smaller than you expect, very high quality and sounds great. I use it every day and it does exactly what I want it to, just like another musical gadget of mine

There is a Whitepaper on the Squeezebox Boom Audio Design which is a very good read.
