Cswood, believe it or not the Polk LSim 707 is a nice sounding speaker it is not exceptional but does a lot of things well for the money. We got a pair in trade and I was actually suprised how musical they are.
Martykl, the Beryilium drivers just have a clarity that brings in little details like breaths, and cimbals, and macro details that are just masked in most other speakers.
The best drivers we ever heard are the Diamond drivers from Acution which have a smoothness with detail that is excpetional the next best drivers are the Persona drivers, which create this immense soundstage with detail that is just remarkable, these speakers do require careful matching of ancellories of they can be a bit too forrward for some tastes.
ATC are very smooth if they are sounding bright than it is something in your system possibly cables, source, or your electronics.
We show the ATC SCM 11, and the SCM 19 we have also had a pair of the 40s which sound like a bigger version of the 40 and in all of our setups the sound is great.
We show them on Naim alot and the match is fantastic, with Wireworld Silver Eclipse speaker cables which has both great detail and has great bass heft, we have compared these cables to both AQ and Nordost cables and the Wireworld's were far better at the same price.
