High Efficiency Speakers Your top 3 or more

I'm just wondering if there is anybody out there who would recommend building a system around a SET amp to an audiophile who listens to a lot of modern popular music, like metal, synth pop, rap/hip hop, etc.

For other more acoustic forms of music solely, I might go there first, but not for those things.

My point about Class D amps is that this technology IS well suited for these kinds of music, plus it does very well with more acoustic forms as well, though maybe perhaps not to the nth degree as might a top notch SET/FULL range high efficiency speaker setup.

BTW, there is a good chance that if you are supplementing the low end of a SET based system with a high end powered subwoofer, that sub is using a Class D amplifier, not SET or even tubes in general.

Is there an generally understood start line for the handle of high efficiency in db/w?

I am seeing some speaker systems under "high sensitivity" that are not that sensitive to my understanding of it Say 93/94 db/watt. The highest I have ever seen is 118db/watt.
