Dynaudio contour with 30 watt amp

I agree with Mattmiller. The Dynaudios love power, and in the end, higher power solid state will give a more satisfying result.

How much power does he need to listen at "very low volume levels"? According to Dynaudio, his Contour 2.8's put out 87 dB with 1 watt of input. I'm assuming that he won't even be using 1 watt, since I do not consider 87 dB to be very low listening levels. So if he is not even using 1 watt, then 30 watts should be plenty.

Yes, you would think so, but in my expereience with several monitors of the same efficiency, a tube amp of that power rating, (a deHavilland to be specific) was not up to the job of really controlling the speakers and making the sing as they should. And that applied at lower volumes as well.

Technically tube amp won't clip but will simply sacrifice the power. To bring these speakers to 87dB you'll need muchmuch more than 1W.

86 db is loud. I believe I listen to music at most at that level.
Is the sensitivity of this speaker measured by "2.83V/m"? 2.83 volt input and the microphone was placed 1 meter from the speaker’s front baffle.

If most of the amp send 2.83V to the speaker, then I only need 2 watts if I sit one meter away from the speaker.
