ss amps with variable input sensitivity

DEFINITELY THE PARASOUND OFFERINGS!!!! Most of the Parasound models offer adjustable input volume pots, and are simply superb bass amps! Infact, the Parasounds, if anything, are really well known for their solid bass reproduction! The are very good sounding solid class B amps on their own mostly, but also shine when used to driver bass on biamp and subwoofer set-up's!
If you are doing it right, you could use a very high refined amp on the top, and the parasound on the bottom, for absolutely superb results in just about every conceivable instance!...that being if your speakers sound good biamped in the first place!
good luck

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.

...sencitivity is the value that you can input for the desirable output.
Usually in specs the input sencitivity is the voltage you need to throw in order to get the maximum output power.

The Xover should have output level controls

parasound hca 1206 and hca 1205 both have output pots on the rear of the chassis for each channel
