Hi, I own an A-9555 that I've been very happy with.  I've been driving 8-ohm B&Ws with it, but I've been thinking of buying a pair of 6-ohm Monitor Audio speakers.  I'm not technically savvy enough to understand more of this writeup that a harmonic appearing with 4 ohms and the general conclusion that the amp is more comfortable with higher impedances.  In your opinion, would it be comfortable at 6 ohms?

Shouldn't be a problem, Alec.
