I currently have a Adcom GFA 5500 runing 4 KLF -20's for my front mains they sound a bit muddy, even with 2 ART 351 EQ's. Was wondering what a good modest tube amp whould be to improve these? I have a Adcom 535 runing my 2 KG 4's rears with no EQ. They sound great. I picked up the 2 ART's thinking I could tweak things a bit. Everyone that listens is blown away but I'm stilll dis apointed. I have a Behringer Ultra Curve Processor being used in my home studio with 4 Mackies increadable definition. Like nite and day with those. Anyone using or experimenting with these processors with home audio?
