Importance of Amplifier versus Preamp?

Newbee, thanks for pointing that out.

Regarding high efficiency speakers, I think that the point Minorl was making and that I was emphasizing would become clearer and less controversial if the reference was to highER efficiency speakers, as opposed to lowER efficiency speakers. For example, say 84 db/1w/1m vs. 92 db/1w/1m, those both being much more common choices than speakers having truly high efficiencies such as 100 db/1w/1m or more.

Using that example, and assuming that the two speakers have similar impedance curves, if the 92 db speaker requires say 50 watts to be able to produce the desired peak volume levels, the 84 db speaker will require 315 watts to do the same (assuming the speaker itself can comfortably handle that power level).

In general, it seems safe to assume that a 315 watt amplifier will usually cost dramatically more than a 50 watt amplifier, if they are both to provide the same level of quality. And the concerns that have been mentioned that are unique to "high" efficiency speakers (as opposed to "higher" efficiency speakers) would seem unlikely to be be particularly relevant at 92 db or thereabouts.

Both very important preamp more so.

The better highly efficient Class D amps out there today, and some are quite good, can deliver 500w/ch or more for comparable cost to lower power Traditional less efficient Class A/B or certainly class A amps, tube or SS.

So you can get efficiencies in speaker, amp or both these days.

Bottom line is you have to get things matched well to keep costs under control. I'd get speaker/room interactions right first using a suitable amp for the speakers, in order to be in a position first to access source sound quality meaningfully, and then tweak the pre-amp and source from there. How can one assess the sound quality of a pre-amp without the stuff downstream needed to make the music in place properly first?

There are some pretty good responses here on this subject. Sometimes we all forget that this can be pretty daunting and more so for beginners in the hobby. I guess that is true for most everything that has a "high end". Watches, cars, audio equipment, etc. You really have to know what you are doing to play and many people get so frustrated by some sales people (trying to get them to buy the most expensive items, or trying to clear out items without listening to what the buyer is all about), or "experts" that tell them to go for the very best, when they may not be there yet in terms of budget, or listening and appreciation levels.

But, I do appreciate the responses and the fact that people here generally won't look down on beginner's or snub their noses at them.

If you are a beginner, tell ups how much you have to spend, what kind of music you listen to and what
your sonic priorities are and we can get more specific. Today there are many very good integrated amps (amp and preamp in one box) which will insure a good electrical match and save you the cost of an interconnect, if $$ is a factor. Also say new or used,
