Thanks for the heads up, but those are a power amp and IIB. I'm looking for a III. I'll probably find one in 5 years. Until then, maybe I'll cave in and get a IV. I like the idea of more cutting and clinically accurate in the 100/150w poweramp, but smooth simul in the IV still sounds glorious. Now if they made a IV with the coliseum pwer amp, that would be amazing. And a rhythm 2 with as much gain as the lead, like they do for their recto series. Quad pre and recto power amp in a shared pwer supply head. The ultimate. Can you tell I want a boogie again? Rant over.
