ss amps with variable input sensitivity

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.

KP to my curiosity and for the sake of my personal education please tell me what is the neccessity for such amp with variable sencitivity?
Thanks!

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.

KP, available on Ebay almost all the time is a second hand Carver AV-705x, 5 channel amp with gain controls for each channel. If you use only two channels, it puts out 180 watts per. I just bought one and have listened to it some now, and it is as uncolored an amp as you can find with plenty of power. Really nothing to criticize about it at all. Easy to buy and sell on Ebay, so you could try it and if for some reason you found it unsatisfactory. it wouldnt cost much to resell it.
