I've got a pair of Paradigm Reference Studio 100's (the 1st generation) currently powered by a McIntosh C-15 preamp and a borrowed McIntosh 2100 power amp rated at (I think) 105wpc ~ 8ohms. I'd like to update the power amp and give the 2100 back to dad. Polk and Paradigm seem to be in a similar class of performance and value, so I figure this is a good place to ask for advice on amplification.
I had them bi-amped at one point with a pair of 2100's and thought it was a pretty killer setup. (basically 100 watts x 2, per speaker @ 8 ohms) Trouble is, I can't afford 400 watts worth of McIntosh power. I'm not an expert on impedance ratings, and current requirements, all I know is these seem to like as much as you can give 'em. I've read the impedance on these can dip down below 4 ohms in certain frequency ranges, so I'm looking for something that will be able to handle that without breaking a sweat. The only real complaint (and it's a minor one) is that the Studio 100's can be a hair too bright in the vocal range at times, but I think this may have a lot to do with the room I've got them in... probably too small, and with very bare walls.
Oh and my preamp has the 12v trigger output, so finding an amp with the input would be a plus.
I'd like to stick to a budget of about $800 or less total if possible. I'm considering new or used equipment with an emphasis on bang-for-your-buck. I know that's not going to get me McIntosh quality, but this will be a solid foundation from which to make improvements later if I decide I want to.
