I believe it. I would love to try those amps. The closest I have played was the fortin super hi Hiwatt. It had a great clarity and a wonderful voicing. But I have heard about the punch from those DR103s. And I have heard nothing but great things about Hiwatts and Reeves ampsWhen I'm wanting tight high gain metal tones I generally stick with the SLO pedal, or Wurm 2. When I'm playing doom/stoner metal, or some classic rock it's one of the fuzz pedals.
Nothing I've ever played through crushes for heavily distorted tones at loud volume like the Hiwatt and Reeves do. They have a level of punch, and clarity to them that is unique. I also briefly owned a Hi-Tone DR103 clone, and it was the same sound.
