I don't know if the HK avr has this, but a lot of the receivers and preamps I have installed lately have had internally selectable options for biamping. Bascially, you lose either the zone 2 or 7.1 capability in order to send the signal to a separate amp.

My clients did not use this feature, so I didn't get to play with it It didn't seem like those AVR's did any sort of crossover or EQ'ing for the biamping, so I don't see what the difference between that and just using a Y cable would be. The Y cable would need a bit more gain to make up for the split loss, but that's hardly worth losing 2 more preamp channels.

Good luck.
Yep, that's right, forgot about that possibility. If your AVR can assign those channels to be the same as the main L/R, you won't need the splitters.

If you do need to use splitters, though, I wouldn't worry about signal loss from the split. The input to the amp will be high impedance, and the voltage at the inputs to the amp will be identical after the split. I would expect no problems.
