Thanks guys. I appreciate you taking the time to advise me. Aedv8sc, thanks for educating me on vertical bi-amping. Will experiment. Bbaxley2, I have auditioned several preamps in my system and have not observed improvement in sonics yet...but will continue exploring! Do believe there is a definite psychological drive in Hi-Fi audio pursuits.....need to trust your ears and your ears ONLY!
