I had SS for decades. Then a buddy brought over a tube amp for me to try in the rig. The difference was like night and day. Even my wife, who really doesn’t care that much, commented on how much better the tube amp sounded.
The last couple of years I’ve had four different tube amps in my rig. Two that friends have let me try and two that I’ve purchased. They are in order: Prima Luna Dialogue One integrated, Dynaco ST-70 power, Prima Luna EVO400 power, NAT Audio 805 Generator mono blocks.
