Dynaudio Evidence Temptation and tube amps?

If you look at the specs on this speaker you see its rated 90dB sensitivity with a 4 ohm impedance.
Tubes do not double power as impedance is halved (if acting as a voltage source they will cut power in half as impedance is doubled).
So efficiency is a more useful spec. In this case when you do the math that speaker is 87dB which in a nutshell means it needs power. BTW, current cannot be had without voltage; the two together create power; I mention this because the term 'high current amp' is a bit of a misnomer).

Your amp employs feedback and will act as a voltage source. But you will be pushing the amp pretty hard if you ever try to play things at a higher level.

4 ohms will also cause the amp to make more distortion- this is true of all amplifiers tube or solid state. IMO/IME if you really want to get the best out of your amplifier I would look for something that is higher impedance, higher efficiency or both. Amps that work hard for a living always make more distortion, and distortion will obscure detail.

My experience with Dynaudios is that they are very hard to drive, they like to be driven loud, that's when they open up and sound their best. I would suggest a pair of Legacy Audios or Focals, these brands typically make efficient speakers that sound great at low volumes, the point being they will be easier to drive with tube amps. I drove my Signatures with the Coincident 34se which is only an 8 wpc amp. And they sounded great with acoustic music.

Thanks to all, decided to buy my buddies Martin Logan 13A's. Running from the 4 ohm tap to minimize the impedance issues in the higher frequencies.

I think ML like power the

same as Dynaudio. I have heard they aren't that tube friendly.

If you wind up with the highs sounding rolled off, you can correct that using a set of ZEROs.
