So I've considered the TecAmp Pumas to be the best of the Class D amps, at least for my interests and purposes. And call me retro, but even as good as the Pumas are, I've been shading back into Class A/B because it seems like the notes have more dimension and attack integrity. But this week I got a chance to hear the new Genzler amp head, through the Genzler 1-12" cabinet with a 3x3" line array, and I was very, very impressed. Solo bass only, but really nice. Is there anyone out there that has experience with both of these heads? Care to share?
