Right now I'm listening to the Allman Brothers (Stormy Monday, Fillmore East) with this amp driving the Infinity Quantum Jrs, and I couldn't be happier.
Note the front to back shafts on the left and right. They allow source selection, tape source and speaker switching to happen at the back of the amp, minimizing the length of critical signal paths. Elegant.
I'm not saying that I haven't seen this before, but it's cool to see it here.
