A little deeper on amp power please....

It has been so long that I can't remember where the original thought of more is better came from.  Given that it's a good "more" not just crap.

I went tri-amp a few decades ago and will never go back.  At the moment using two Pass mono X260.8(s) and two Pass x30.8(s).  I must say the sound is effortless and yes I really let it have at times.

The beauty is that some thunderous bass doesn't change the mid or highs because they don't know what the hell is going on. Headroom is good for the soul.

YMMV

Good post.

Think of it as low end grunt you have effortless power at low end instead of thinking it as a car with high horsepower think of it as one with a lot of torque that can push you off the line effortlessly... It does make a difference

Glad that current delivery came up soon here.

Although many other factors reside in dynamic response, current capability and response to impedance dips seem to rise to the top in my experience. Factoring in that all speakers are different in how they behave with any given amp or amp topology, that the type of music is also a factor, even cable guage for that matter.

But there really are so many things that can occur differently between systems of higher power with lower sensitivity and those with lower power and higher sensitivity. Even if dynamic response can be noted as similar in any given section of music (with volume matching), there can still a difference in tonal character and decay. There are reasons why many gravitate toward low power, high power, or something in between. But what seems to remain constant is that need for sufficient headroom, at least relative to the needs of any given listening environment (types of recordings, near field or large area etc.).

I think that in addition to power, there's the issue of feedback vs. output impedance. 

By using massive output stages (relatively) you reduce the need for feedback to achieve low distortion.  This tends to only work with high power amps, but surely not all of them.

I suspect that a lot of what we think of as the need for power is really the need for high current, and that with ideal 75-100WPC amps with many output devices and low feedback we'd be very happy.
