Given you have an allergy to pre-owned stuff, have you thought about actives?
Most of the owners of AVI describe them as defying science, but they could well fit your budget and love of deep bass -- you could add a sub with a pair of DM5s and still have change for a weekend in the country.
(No, I've not heard them, nor do I want them)
I highly recommend the DM5 with the AVI subwoofer. I couldn't be happier with mine as I've never heard any other system which I prefer.
You can read my impressions of the DM5's and the AVI subwoofer here in posts number 1, 38, 47 and 49.
Clicky
But that said, I suspect that the larger AVI DM10 speakers for the same price as the DM5's plus subwoofer (£1500) would be the better option for most peoples needs. I chose the DM5's over the DM10's because I like small speakers for near field listening at a computer desk and the deeper bass that the sub provides comes in handy when watching movies, playing games and listening to electronc dance music that I'm so fond of.
But if it's purely just a regular music system and you're not too bothered about having a subwoofer to give you ultra deep bass that goes below 30Hz for movies and stuff then check out the DM10's. They have deeper bass than the DM5's on their own, go much louder and have slightly better clarity (which I struggle to imagine considering the DM5's are the clearest speakers that I've ever heard). Or if you can stretch your budget to £2300 you could get both the DM10's and the matching subwoofer and have the best of both worlds.
