ss amps with variable input sensitivity

Not many amps have volume controls anymore and with good reason. The volume control affects the sound probably more than any other device in your system. A bad one makes bad sound. And having an amp and preamp both with them can make for a bad combination.

I believe parasound made some earlier amps that had volume pots. Can't tell you anything about the sonics of those amps. Most of the earlier parasound gear are probably well built even with the pots.

Hi KP. Just noticed your new thread following our active-xover discussion. The only SS amps with some adjustment that I've heard of are ones which have a limited number of discrete gain levels that can be changed by the owner. For example, the Rowland amps, and the Gamut amps (there are others). I personally own a Llano Design Trinity hybrid amp, which has tube input/gain stage but SS MOSFET output stage. It accepts a wide variety of small signal tubes, and I can change its overall gain (and sound character) dramatically by rolling the (two) tubes. This amp might be a way for you to match your Rogue amp in a biamp situation; the Llano is more likely to blend with the tube amp, yet it provides more slam in the bass than many pure-tube amps (it's not very expensive either). Send me an email if you'd like more details.
