I envy you the amp (I have the speakers) but think you'll have to try the two approaches and see what sounds better. I would guess that using interconnects (to the SA amp) would sound better, but it's JUST a guess. Good luck, Dave
BTW, I used HSU subs with my former speakers, powering them with a nondescript SS amp via the Hsu's electronic crossover factory-set at 43 Hz. This sounds a LITTLE better than using the same amp to power the Ref 3s' second voice coils, but the SA amp has to be better than what I'm using, so it's not a fair comparison. I'm dying to try the SA amp.
