@ Isochronism, I did not know you had this equipment!, cerwin vega and JBl is my all time favorite for p.a. speakers, rest assured, your vega 18s would desamate anything in the high-end audio for sheer air movement alone, LOL! a krell would kick on this, how do I know, I have done this before!, I had a Krell fpb 200 on the cerwin vega v15E p.a. speakers, 6 ohms, 106 db sensativity!, that was awsome and very clear after I out fitted everything with the best of polycrystal resonance control, I put thousands of dollars of this stuff on this set-up to great effect!, till this day, the most musical system I have ever heard in my life, bar none!
