I've never owned one of these amps in the past, but I hear nothing about them, even here. I know a lot of musicians use them, but is there anything inherently wrong with this brand?

Do they have a high failure rate or a history of problems? Is the sound fairly generic for a tube amp or are they so narrow in their color that they only do certain types of music?

Why aren't these amps seemingly as popular as the other amps like Marshall, Fender, and VOX?

I've been thinking about a Dual Rectifier lately, but I see very little on the internet and I know no one who owns one. Makes me hesitant to make a purchase. They say no news is good news, and I'd like to believe that, but I'd like to know a little more first.

Sort of the same thing with Hughes & Kettner. No one talks about them. I almost bought a Switchblade a few years ago, but the store ran out and I needed an amp right then.
