That was very interesting. I have always been a huge fan of the Bozak. Hated the UREI when it first came out. I do however agree with Scott, the UREI has a sweeter High end and not as big of a punch on the low end like a Bozak.
Never heard the V6 but I do prefer tube amps over solid state. Yes tubes have distortion but as weird as this sounds it warm and pleasent distortion.
Nice review Scott.
