Question on speaker sensitivity / power.

I was looking at some Opera Callis bookshelf speakers and noticed that they are rated for 50 watts max and have a sensitivity of 86db. I would think speakers with that low of a sensitivity would actually perform best with a more powerful amp. Am I off base on the power/sensitivity issue?

Dear Chrizmontes: You are right on the power/sensitivity issue.

There is not much to write of what already posted Rich and Rodman999999 other than take in count that the speaker impedance goes as low like 3.2 Ohms that it is not a very friendly to a tube amp. Anyway try to match it with an amp with very low output impedance: say less than 0.3-0.4 Ohms.

Regards and enjoy the music.
