I run my Maggies thru a BAT tube preamp on the HT for l&r. At one point I ran the l&r via preout directly into the power amp. It sounded great either way, the power amp being the common denominator here. But I think I prefer the tube preamp.
I'm pretty sure the signal does pass thru the tubes, because I can adjust the level of the HT bypass in the options menu of that input.
I never really did an a/b comparison, so I can't say for sure, and I don't critically listen to the HT system. I can say I'm satisfied using the tube preamp in HT bypass mode, and the soundstage it throws is quite nice, I think better than the HT system alone.
