The reason i bought a Triple Rectifier was because i previously had an amp the was nowhere near loud enough at stage volumes for when my band played venues with small to no sound systems. I wanted an amp that woud be able to be heard wherever, whenever--no questions asked. I got it in the triple, and can even give most sound systems that aren't at least 16 channel bus systems a run for their money without being mic'ed. WITH ALL THAT SAID, i still enjoy playing this same amp at bedroom levels, getting nearly the same tone and gain structure as i do live, granted sometimes i do crank it a little when the folks aren't home, hehe, but i have to say that my amp sounds good at any volume, anywhere. SO, if you do plan on playing in a band sometime soon, i would recommend buying the amp that you want, and since you have the money, i say go for the Dual. Plus, with the Dual you have the 1/2 power option as well. Trust me, if you're heart's set on it, like i was and still am, you won't be happy with anything else. Good luck Jakk.
