Sashav, may I ask how do you compare the active PMCs with active ATCs in their respective classes? The passive IB2i sounded pretty incredible to me. I can't imagine how much more the active models(PMC or ATC) would bring to the table when compared to the passive IB2i. Do you find the active PMCs or ATCs to be overall better speakers than the Wilson Sasha and Revel Salon2? A friend of mine owns both these speakers -Salon2 in his main system and Sashas in his bedroom.
I am also familiar with the Harbeth M40.1s. As good as this top of the range Harbeth can be, the philosophy in the design of this speaker is different from the equivalent range from PMC and ATC. The bigger PMC and ATC passives or actives are made from robust heavy duty drivers built in heavy cabinets whereas the cabinet of the 40.1s are made from "thin-wall" panels. I believe the bigger PMC and ATCs possess a much larger scale with higher SPL capabilities than the 40.1s(or any other speaker for that matter). The result is a highly controlled and composed sound with high degree of transparency and the ability to play at crazy volume levels(probably in the excess of 120dB in a large space) without losing control.
