I've never used one, but they sure look nice. I regret being such a gear snob when I was younger, as I was sold out to whatever brands my heroes endorsed by their use. By the time I grew out of that, I had kids, and gear was a luxury I couldn't justify to myself (or ... and perhaps
especially... to my wife).
I feel like I'm going to may have missed out on something I never knew was good. I hate it, for example, when I discover how great an artist is post mortem. From what you say, I am now a bit worry that I may have a similar experience with an amp brand.
