ss amps with variable input sensitivity

Hello, Ral, nice thread transition, eh?

Marakanets, I'll abridge the XO thread:
Alber suggests I passively biamp my vr-4's.
Rogue 120 magnums on top.
Since I would to be using an active XO, I need bass amp(s) with adjustable gain.

OK, so if the Rogues have a sensitivity of .83v, and the Parasound that of 1.0 this means that the Rogue will play louder at any given volume setting than the Parasounds; correct?

Also, I imagine that the sensitivity adjustment on the Parasound can only attenuate the signal, not boost it.

In this case, this combination would not be practical. question mark.
