The difference between tubes and solid state that I am finding

I'm still a newbie when it comes to tubes. I have had the McIntosh C12000 preamp (with Moon 861, Eversolo A8, and Focal Sopra n1s) for awhile now. It is very enjoyable. I noticed when switch between Tube amp and Solid state mode the difference is very subtle. But when I do focus on it, I notice:

Tube sound: More open with a slight blossom sound. Maybe slightly more holographic. A pretty sound. 

Solid State sound: More exact. Instruments seem more there and defined. More in my face. Bass hits harder to. But not as open and airy. 

As far as brightness, I wouldn't say ether one is more softer than the other... the brightness seems same on both. 

Am I correct in this is how the differences between the tube/states differ?

I really enjoy both modes.... but I think the solid state one gets me a little more excited.
