What's "next door to Camden" supposed to mean? Is that estate agent speak for Archway or something?

Anything can be improved. It's just as likely that any particular individual would prefer ATC's implementation to yours. Speakers are all about personal taste, none of them are anywhere close to perfect.

I've heard ATCs sounding distinctly average, and I've also heard them sounding very good (Bub's count in the latter btw). Can't say I've ever heard a pair of PMCs that I wouldn't want to set fire to rather than listen to. But that's just me.
