Amplifier current vrs watts; why is current more important?

Unless you have a very benign flat impedance speaker (rare) that doesn't wander to much from being a flat impedance between 20hz to 20khz, only then is an amp with watts but little current OK.

You need an amp with both "watts" to suit the dB efficiency to get the loudness you want, and "good current" to keep the "loudness" you want during the "low impedance" dips (that nearly all speakers have).
This stops the amp becoming a tone control, and modifying the flat frequency response. Just as in the graphs I put up.   https://forum.audiogon.com/posts/1730185

And for me, that’s OK and perfectly fine. A little response tailoring often suits me. It’s not your place to decide what’s OK for folks.
It’s just that we don’t all want that.

  
No need to get your knickers in a knot.

That fine, if you're willing to take the chance, as the "response tailoring" as you so quaintly call it, will be different for every speaker you put it on.

 So you never know if your going to like the "tailoring" it's doing until you bought it.
BTW: It's still a tone control that doing EQ, which ever way you look at it, which will be a different EQ for every different speaker.

Get over it.

Bit rude! that response for being shown the truth. After all it’s what the subject of this thread is all about.
Educating is a form of telling, and if you don’t want to learn why current is needed from an amp, and what happens when they don’t have enough for the load they’re seeing and become tone controls because of it, then don’t listen or partake in the discussion
