power/impedence reciprocity

What would you rather have for a medium sized room: an amp that does 125/250/500 watts into 8/4/2 ohms, or an amp that does 250/325/500 watts into 8/4/2 ohms?

It has been explained to me that the 125/250/500 will give more slam, low end detail and control than the 250/325/500. This is because all speakers will go below 1 ohm for short durations during drum beats and other low frequency percussive sounds, and the 250/325/500 falls off more quickly with the load that by the time you get below 1 ohm (or even below 2 ohm) it can't handle the low end nearly as well.

I have always suspected this to be the case, but would like to check my suspicions with some techies. Thanks for the advice.

That is, as you say, "a totally different matter." There is short discussion of what Class A is at www.audioasylum.com/forums/set/bbs.html Just look for posts within the last couple of days.

Two separate threads titled "Why class A" and "Is anyone interested in what class A means" explain it fairly well.

Also a recent thread at www.bottlehead.com within the last couple days.

Seems to be the issue of the week.

Personally, being a tuber, I would never buy a speaker that did not present a fairly consistent and benign impedance curve and was at least fairly effecient. Frankly, I think I would do the samething w/ SS where clipping is so much more of a wake up call.

I remain,
