What does more power do for Magnepans?

For an understanding of audio output in db, and power requirement, read this:(http://www.axiomaudio.com/power.html) It would be nice if doubling the perceived sound only required doubling the power. The least I've powered Maggies with was a slightly modded Dynaco ST-70(about 17W a side in reality). Yes- They sounded nice, but realism could only be approached listening to small acoustic sets. Remember that you're driving a nominal 4ohms too, and look at your amp's output into that load before you shop for power. I'm trying to think of ANY live music I've heard in the last 48yrs that was, "lush, thick and gooey." Was it the 'Hot Fudge Sundaes'? NO-that was at Baskin-Robbins. Hmmm, let's see.......

Your 9200 has pre-outs and 200wpc. If you were to purchase a Plinius P10(also 200wpc) you could bi-amp very simply. Magnepan offers an optional bi-amp x-over for the 3.6/R, and I'll bet one is also available for the 3.5. You might give them a call and check.

Pa1- I really do think you will be surprised at how relieving your amp of having to reproduce bass/mid-bass can clean and open up your overall sound. Can you find a dealer that will let you audition one for a week or better? That would give you time to burn it in a bit before listening critically.

The biggest problem with that calculation is that to obtain a subjective doubling of loudness requires ten times the amplifier power. See: (http://www.gcaudio.com/resources/howtos/voltageloudness.html)
