Importance of Amplifier versus Preamp?

I missed what speakers you have?

I'm not sure HE speakers makes choosing amps any easier. HE speakers tend to be sensitive to everything, including noise. It can be like listening under a microscope where any difference good or bad is apparent. It seems to me that those who go with the HE approach end up with perhaps the most expensive electronics as well before everything is good. Its true that not many watts are needed, but all teh rest probably matters more. IF using truly HE speakers that is.

Yes, getting an integrated means an expert matches amp and pre-amp for you. Assuming suitable speakers, nothing too challenging or esoteric, and not an unusually large room, you are probably good to go sooner and for less money than otherwise.

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?
