I agree with ray1234 having tried both possibilities. Using the pre-out allows SAM on the mains, which makes the perceived bass even better and adds woofer protection.
I happen to use the pre-out socket on the companion, works fine for me. I have one (mono) sub connected to the 440.
The REL representative is worrying that the Expert has a constant offset voltage reference on the black speaker outs, which is indeed the case for B&O Ice. But the Expert does not; the voltage is 0.
So I can confirm that when using high-level subwoofer connections, choosing a negative (ground) speaker terminal on either Expert works just fine for the REL black wire. I also tried the ground thumbscrew, also fine.
