Why is everyone *****ing about the price of these amps? Yes they are costly, but look at the other brands in their range. Tru Tech, Helix, etc all cost almost double for what you get. I was quoted $450 for the tu600 tube amp from a local authorized dealer. All I got to do is sell of my DLS amps and I am all over these amps, great stuff. In fact, US Amps is one of only 3 amps that Dynaudio recommended I used on my comp set. And Jeff Coleman cant say enough good about a Dyn set on a tu600. He loves that combo. You really cant get the same quality as these badboys in a cheaper priced amp, just not going to happen.
