Great thread Ernio 1. My uncle has a VERY nice two channel system consisting of Magneplanar 4a, audio research pre, CAL cd player, Bryston amp. I have ML Ascents, his old phase linear 400 and audio research sp4, and Sony 508es cd. We both agree on both our systems that one of the best live, if not the best live cd listened to is...a King Biscuit Flower Hour of...DAVID CROSBY recorded live April 8, 1989 at Philadelphia, PA. Any Crosby, Stills, Nash and Young fan needs to check this one out! Awesome!!
