I've often wondered what inspired Mr Brennan to make the B2 so small. I'd much rather have had something with a fascia large enough to accommodate an off/button (my model doesn't have one at all), headphones and the USB ports all on the front.
I get the impression most people, on this forum at least, use their B2 as part of a larger set up in a "proper" hi-fi scenario so the benefit of just having it on a desk with a couple of small speakers, which I think was the original intention, isn't important.
