How much if any difference could I gain from changing to a pro amp to drive my IB. Right now I'm using a single PE 250watt plate amp (no Boost model) & running 4 Dayton DVC 15's in dual manifolds. I am really happy with the way things sound but curiosity has the best of me. Plus I have another use for the plate amp in my basement if I upgrade. I was thinking of using a Crown XLS 402 to replace it, & most likely will finally add a BFD to the system as well. Thinks in advance for any thoughts on the matter.
