![]() ![]() ![]() ![]() Info on damping factor (the Wikipedia article is kind of questionable to me): It's not insignificant that better sounding home amps weigh a LOT more than bad ones, with virtually identical RMS output ratings. Incidentally, reviewing these figures is what guided me away from certain very popular brands of home amplifiers in the 80's and 90's to a Harman/Kardon AVR-20 and eventually a Yamaha RX-V995 (sold to me by none other than the legendary Bob Heil no less). With that in mind, and remembering that watts = volts X amps, it's easy to see why a 20 watt tube amp will fracture your molars whereas a cheesy little Pioneer 100 watt A/V receiver trips over itself every time Michael Bay blows something up in a movie - the latter have no 'mahrbuls'. more accurate - the amplifier will sound. The higher the slew rate (meaning how much power could it deliver how quickly) or damping factor, the 'better' - i.e. In short, this is the amplifier's ability to precisely control the motion of the transducer - the slew rate was measured in volts per second, whereas damping factor is something different (it's on Wikipedia if you're bored). Anymore I think the prevailing measurement is "damping factor". There's a measurement (or was) on amplifiers that is a far better indicator of how well it will push a given speaker than the RMS rating, and that was "slew rate". Tube guys recognize this to be true, but few people I have talked to about high-end audio can place why. In my teenage years when I became fascinated with audio, I was fortunate to meet an engineer who helped me understand that wattage isn't actually isn't much of anything in predicting loudness or quality. ![]()
