power not too much? How? No questioning you. Trying to understand. What should I upgrade too power-wise (not a model, just specs)?
People will give anecdotes saying otherwise, but careful study suggests that it is often an audiophile myth.
The audiophile argument is that when you clip music you always increase the energy that is sent to the tweeter because clipping adds harmonics to the music.
Reality is that clipping music can definitely change its harmonic structure, but the change can go either way depending on the music itself. Many modern recordings have a ton of high frequency energy, and clipping actually reduces the high frequency energy in them. Clipping makes them sound muddy, which I hear happening more often.
IME musical recordings such as orchestral recordings will probably have their high frequency content increased by clipping, but much good bright modern rock and roll will actually suffer a decrease in high frequency energy due to clipping. I have measured this on the test bench.
The remaining effect is that a more powerful amplifier can deliver more power and in the end it is always more power that damages the speakers. The question is how does that more power get applied - by clipping or by simply turning up the volume?
I can see where a person who listens to a certain kind of music and gets clipping with a smaller amplifier, will put in an amplifier that has more unclipped power, then avoids the clipping, and if the listener doesn't exploit too much of the added power, he might save wear and tear on his tweeters.
I feel that in general, and this is more of an opinion than an actual scientific fact, that swapping in a more powerful amp will usually result in more power being applied to all of the drivers in a speaker, and thus there will be a greater possibility of speaker damage. If the new amplifier has considerably more power, this is much more of a possibility.
Many of the amplifier upgrades I hear about are fairly minimal, such as adding a 150 or 200 wpc outboard amp to an 100 wpc AVR, and it is more likely that a person who really doesn't push that much harder than the ACR can do unclipped, will indeed save his tweeters with the larger amplifier. If you want your system to play twice as loud you would need a 10x more powerful amp, and few audiophile power amps have that sort of power.
