Where’d I ever suggest an F5? There’s precisely 100 Pass built F5’s in the world. Good luck to anyone finding one. Last I read the OP was asking about an INT-60. You don’t know what you’re talking about, pure and simple. 30 watts of class A power would drive Sasha 2’s just fine. They’re 92dB efficient speakers and are only going to demand 5 or 6 watts of power on average in his room if he prefers his music loud enough to do hearing damage. The INT-60 would be more than adequate. Sure, transients are going to demand far more power on peaks, and yes, the impedance dip is brutal, but none of that would pose much of a struggle to any Pass amp in production.
