Geeez - didn't know you wanted a history......
First "real" amp was when I was like 14, Peavey VT Classic combo, or something like that,
Ross distortion pedal.
When that wasn't loud enough for playing with a band, I bought a Mace head and a UniVox 6 x 10, that setup lasted about 5 years.
After that, I had a couple G-K's, the little series II combo for practice and the rack amp for live, I can't remember that model, I think it was blue and red screen printed on the front panel, with a stereo cab.
The whole time, I was gassing for anything Marshall, like for 10 years I played everything I could get my hands on that said Marshall. By the time I could finally afford one, the local music store got in their first 5150, I'm friends with the owner's son, and we cranked that sucker up very very loud in the store.
I ended up taking it home with me, and I was completely satisfied with my tone for the next ten years. Oh, the first thing I did was to throw away the Peavey whatever tubes and put in a set of Sovtek coin base 6L6's.
Then I had a college kid working for me, he had a Bogner, his two roomates had a Mesa Recto, Line 6 and the Revolution. I went over to his house one night and played them all, but the Revolution just totally blew me away. The cleans were awesome, too. After that, my 5150 just sounded muddy and hissy and noisy. I went crazy with preamp tubes, sent it back to Peavey, etc. etc. So about a year and a half ago,
the roommate decided the Rev was too much for playing in the living room, so I bought it from him and have been in tone bliss ever since.
I have not played anything real high end like Diezel or Engl or Cornford, never seen one in person.
I've played everything new that comes out from Fender, Marshall, Peavey, but I haven't liked any of those over the past 12-15 years.
