    Hi, I'm looking to bi-amp the woofer section my NHT 2.5i speakers with a power amp. However, to ensure that the woofer section matches my tweeter and midrange, I need to be able to control or vary the amount of juice that gets fed to the woofer. I know some power amps allow you to adjust the amount of gain, level, or volume (e.g. a Crown professional power amp allows you to do that, however the fan noise is distracting for home use or the bulky NHT SA-2). What brands or models of power amps have that capability?

    I think many monoblocks have this feature. Also the audiosource amps have adjustable level controls.

    I am not sure what your budget is but a good passive volume control from a company like Creek can be had for under $150 used.

    Might open up your options

    Do you mean Input-Level Controls? The NAD C270 has them.

    I could name a few brands that have a built-in attenuator, but I have never seen someone is going to do a passive bi-amp mention the need to adjust the gain on amp or the other.

    This might be because they are perhaps paying attention to the overall gain of the amp and its input impedance.

    I go to Audio Asylum and do a search on passive bi-amping to find out.

    I am pretty positive however that the worst option available would be to have a separate attenuator on one of the amps.

    Marantz MA6100?

    Will the Marantz MA6100 Monoblocks have that capability? Does anyone know?

    Thanks for the idea of the attenuator. I suppose that that is probably what these amps have inside them anyway? It should indeed open up a bunch of options. I wonder if the level/volume controls (including equalization) from Hsu or Cambridge Soundworks would do the same thing???
