I used to ride my bike to Radio Shack several times a week and just dream about having a fancy stereo, cb radio, etc. One of the family friends upgraded his hi fi to stereo and donated to me his Williamson tube amp and Heath FM tuner. I then was given a huge home made speaker ( 4.5x 3.5x 3.5 feet ) with University Drivers and crossover. It was mono, but you could hear it and feel the bass across the street. Later as a teenager in the 70's, I saved up and bought a Kenwood KR 4070 receiver. Finally I had state of the art, no warm up time. When I first turned it on, I just sat there wondering what was wrong... It was loud, but not nice, not musical. But I decided that is the way recorded music is supposed to sound, and I moved on. Fast forward 30 years and I friend hooked up a nice tube amp one evening. All the memories of beautiful music came back. The next day I went on a tube amp hunt. Ended up with the Cat gear. At the time I owned a very nice pair of Classe CA 300's in monoblock. I have heard some of the best solid state amps out there including the Mark Levinson 33's, Halcro's, etc. The Cat amps sound better to my ears. I will never go back to transistors for my main stereo system. Magic in those tubes!!
