This is probably mostly of interest to those in the UK, because that's where the prices are relevant. Consider this a pubic service announcement :)
I had a spare Connect:Amp after buying one of the new Amps. It was sitting forlornly in its box, so I was looking for a pair of relatively compact and inexpensive speakers to partner it with, to return it to usefulness. I settled on a pair of Q Acoustics Concept 20s, and I ordered a pair without listening to them beforehand. (Yes, I know.)
They arrived today, and I'm really, properly impressed with the sound quality of the resulting system. They're a perfect match for the Connect:Amp's power (and more than loud enough for me), and if you buy the white version they're also a perfect match aesthetically, with their white and aluminium construction. In my view, this system is something of an excellent audio bargain, with the Connect:Amp discounted at £399 and the speakers discounted at £279. You're getting a lot of sound quality plus Sonos integration and convenience for £678.
I also happen to prefer the look and build quality of the Connect:Amp over the new Amp, but that's probably just personal. The Concept 20s also have high-end build quality.
Anyway, I have no skin in this game. I just think I've stumbled on a very good system pairing, so I thought I'd share.
