Thinking about your situation, why do you feel it is your power amp that seems to be the weakness ? I read up on the amp, and some users are saying it was better than their QSC and Crowns, both of which I owned many. In my remaining arsenal of power amps, I have some Yamaha pro amps and a Smart Theatre Systems TA 242 ( a Hafler 220 on Steroids, biased in class A ), and they all do very well on my Klipsch Lascalas and Heresy 2s. Not to turn this around, but, I have owned Vandys, up to the models 3, and although I understand Tomic and others being fan boys, they were not my cup of tea ( not just Vandys ). Maybe you should step up to the 3s, as they will give you " more ". What other speakers have you owned ? Again, I am not looking to start any trouble here, but, being a retired audio consultant with quite a bit of experience with lots of equipment, I am just saying. Another thought would be, to get a powered sub, and if possible, with some crossover that can roll off the Behringer / 2Cs from handling the last octave or so, and take over from there. The Vandys will be more open and dynamic, and it might be that difference you are looking for. These are my thoughts. Over and out. Enjoy ! MrD.
