Russ69, I have considered trying tubes, but am afraid I would become addicted to them also. In fact a retired Airforce pilot has talked about selling a pair of McIntosh tube amps he had. (Maybe still has). He bought one of them assembled and built the other from a McIntosh factory kit. 20 or 30 watts apiece if i remember right. I guess I should talk to him some more about them, but am afraid I would walk home with less $$$ and then have to re-tube/referbish them. I don't recall the model number but seems I read somewhere that volume can be adjusted by using the gain control. He never said anything about a preamp for them. He has Given my wife and I several Items that look like new (surround sound reciever, center front speaker, sub base speaker, TV with entertainment center) when he decided to upgrade his systems. So he appears to take exellent care of his possesions. Good person to be friends with, but I would not want him mad at me.
