I do not have personal experience with tubes in my own system so my comparison is my long experience with SS versus George Merrill's set up in Memphis. It was not a top of the line Tube system but it was the most musical set up I had ever heard. Pls note , a system IMHO is more than a single component and his components were well matched. It was like live music in a well design music amphitheater. I have put together a pass labs SS class a system with a RCM Sensor 2 phono that is very similar to the sound I heard at George's place. I find the pass SS sound in my system is fast, accurate explosive, but can take on the delicacy of a musical piece like Ravel's Bolero.
I am not trying to hype or review pass labs but rather say SS on Tube systems can sound similar and great. I think it's the art of matching components as much as it's the genealogy of SS vs Tube
