I actually bought the Diablo utopias as well. I listened to them at the dealer's showroom with great tube great as well as good solid state. The tube combos were A/R and BAT and the solid state was Mcintosh and Halcro. In this comparison, I like the solid state, very much in line with what Elviukai is noting. I also tried them on a recommendation in a friends's system with his great solid state amps, Burmester, and that was the golden match. Needless to say, I am going to get the Diablos to play through Burmester soon. I have Burmester in my other home and did not get the chance to try this setup logistically but now that I have, I am convinced it is the way to go. I hope this helps.
Can Focal Diablo Utopias be paired with a tube amp
I have recently purchased a pair of Diablo Utopias. My dealer suggests that they be powered by a 200W per channel solid state amp but I have developed a real love for vacuum tube sound. Anyone out there know of a successful pairing? Thank you very much for your help!!
