Tube vs. Solid State Amplifiers

I have followed these discussions with great interest over the years in search of the best solution for me.  I most recently went through integrated SS amps from Parasound and Hegel, then graduated to separates with a Prima Luna Evo 300 preamp paired with an excellent YBA Passion 400 SS amp rated at 100 wpc to drive my Harbeth 30.2s.  I still felt something was missing, so added a single REL T9i subwoofer after being convinced that it would be a better addition that rolling tubes in my Prima Luna.  The REL is compelling, but I still wondered if I needed more amps.  I wasn't looking for louder, but fuller and bigger sound.  My search ended with the purchase of a tube amp with less rated power than my SS amp.  A dealer kindly agreed to come to my house to A/B my YBA against a Rogue Audio ST100, which is rated at less power than the YBA.  After about two-plus hours of listening back and forth, I concluded that the Rogue Audio tube amp sounded more musical, fuller and more dynamic in Triode mode than the more powerful YBA -- which is an excellent amp!  I never find listening with the Rogue Audio ST 100 to be in any way fatiguing and am a very happy camper.  After years of being convinced that I was not and never would be a tube guy, well, I'm a tube guy.  This obviously doesn't solve the mysteries of SS vs tube amps or how many watts, but I must admit I was surprised at where I ended.
