Hi Chris, the MkI Sasha's they are a pig to drive and need current, and the Gryphon Diablo Integrated looks to me as though it will do that job much better that your AR Ref-150 can, this is maybe why you liked it so much.
As the Gryphon can do 250Wrms into 8ohm and 800Wrms into 2 ohms, which says to me it has bi-polar output transistors just what the Sasha's need, it can push good amounts of current into the Sasha's low impedances.
Don't compare it to the Perreaux 2150B as they are Mosfet output transistors and would have a hard time to do any where near those sorts of figures that the Diablo can do.
I think you will hear a big difference in the bass where the Sasha's load is the worst (3 ohms and –43° phase angle) and they dip even further to 2ohms but the phase angle is no so bad at that frequency.
