well, a few years ago (in a Galaxy far,far away....Denver) I borrowed a old Dynaco Tube amp and tried it out on my old system. my wife and I were floored by the sound!...we listened to some Louis Armstrong, and we honestly had to check to see if the old guy was playing in the next room. we listened to some Tony Bennett and once again, the vocals were killer. I wish I could find some tube equpment around my little town. but, I kinda live out in the boonies in TX.
