George: even with the smaller Diablo 300 intergrated, the mid range and highs seem to “float” and the speakers almost disappeared as you correctly stated. But I was also very impressed with the bass.
Yes to me the Gryphon’s are one of the best commercial linear amps anyone could listen to. Especially the ones that are high biased into class-A or adjustable bias for that Class-A sweetness, like the Antillion’s, or the older fixed high bias DM100’s
And because they use bi-polar (bjt) output transistors with big power supplies, they can drive down into low impedance’s far better than tube, mosfet, hybrid, and present day class-D.
Cheers George
