Recommendations for best most efficient speakers

Thanks for the article. I knew some of the topics discussed, but it was very informative. It still begs the answer of better efficiency for lower powered amplifiers. Although there was a great point made by Celtic66 and the inference made in the article. High efficiency does not equate to high quality sound. I have a Jolida JD-202A, which is fairly good integrated tube amp and should conservatively drive most of the speakers out there, including those that are in the sub-90db range. I guess I just need to take the suggestion and lug my tube amp around the shops and have a listen.

Thank you Audiokinesis for the clarification. It seems logical and I am really tempted to test the waters a bit more before diving into loudspeakers.
