I voted no, but I run 1000 watts. I don't need it, but it was a cheap Crown XLS 1000, so why not?
Thing is, powerful amps are so cheap and light nowadays, they've sorta become just something you can easily do, rather than something you aspire to do.
I remember selling stereos in the 70's when all the big changes were really taking place. Cassette decks were getting better every year. Real breakthroughs in direct drive turntables and speaker design were happening all over the place. Everyone who was into it wanted that $99 AR turntable. Stacked advents were huge. Nakamichi cassette decks. And if you had a pair of pristine ADS L810 speakers today, they would blow the socks off most of the speakers people use today.
And here we are, 50 years later, and I STILL use my 1977 turntable and amplifier. The stuff reached a plateau and became a commodity for most people back in the 80's with the advent of the CD. It was fun to aspire to bigger stuff, when most people could not afford or justify it. Now that a big powerful system can be gotten for the same price, in 1970 dollars, as a starter system back then (and back then, starter really meant STARTER), the fun of acquiring it has almost been taken out of it.
So, I have the power because it cost just a bit more than getting far less, so why not. Meanwhile, If I ever actually NEED that much power it is because the stage volume is too %&$*&^ loud or the band or venue has scrimped on the PA, neither of which is acceptable. Nowadays, the only thing you need your rig and amp for are:
1. Backline - something for YOU to hear.
2. Small gig that doesn't really need a PA except for vocals (and kick drum. ALWAYS mic the kick drum).
For everything else, you have FOH.
And it's only getting more so every day.
