I've had a pair of Klipsch Chorus (I / front ported) for about ten years now. On a regular basis (let's say once per day for 5-10 minutes) I enjoy listening at a fairly generous volume. I'll ramp it up until I start getting nervous or the turntable starts feeding back. Better than coffee. Recently, I started noticing a "flapping" sound when trying to reproduce certain [lower] frequencies at high volume. I pulled the grille, and sure enough there's physical damage to the surround. I've resolved to have both drivers rebuilt locally by an individual who comes highly recommended. I'm interested to know if there's a general consensus as to whether the McIntosh MC-2505 is an appropriate amplifier to drive the Chorus speakers. I've been pleased with the sound of this combination over the years and am generally not motivated to make any changes. However, I understand it's better to use an amplifier with a wattage rating at least equal to the wattage rating of the speakers (or am I mistaken here?). I certainly don't need the capability to generate more volume, but I would like to optimize the speakers' performance at the high volumes I already enjoy. I don't really have existing problems with distortion but I am concerned an amplifier -> speaker mismatch could shorten the life of the drivers once they're repaired. Thanks very much for any thoughts/opinions you all care to share!
