From the spec, it looks a median level tower speaker (one tweeter, one mid range, one woofer). Power is ~100W, so the receiver need to match or close to it per channel. Some what lower power is ok, which is price related. Obviously, you need more than one speaker for a system, so pay attention to per-channel output of the reciever.

NAD is a good brand, but not sure whether it is available in UK.
