Speakers that are good with tubes

Any speakers with 95dB or higher sensitivity.

Have you already bought your "high power" tube amp?  IMHO, tube amps perform best at low power and the high power amps are a compromise to try to accomodate less sensitive speakers.  I know this is a very broad generalization and people will disagree, especially those owning higher powered tube amps.  

I listen at 1/4 to 1/2 watt per channel 98.44% of the time and most people listen below 1 watt when using sensitive speakers.  

I just piecked up an amp to play with that is less than 2 watts per channel.

Many of the pitfalls users are describing that torpedo  tube amp performance are just poor speaker design.  So I'll add to my suggestions:  Buy a well designed speaker.

It does not have so be 8 ohms or above.  My speakers are 4 ohm, but they are very, very flat and very well designed.  I bought them to use with an ss amp.  The first time I heard them with a tube amp, I promptly sold the ss amp.

@hide45  Good summary.  Hopefully the OP hasn't bougth or at least married to a tube amp yet.   To me they should be bought as a pair, however, there is a lot of wiggle room in choosing both.  For example, I recommend an SET.  However, my current primary amp is not an SET, it just sounds like one (Decware ZMA).   A lot of people like horns, I've never found them to suit my preference.  I am currently listening to a very well designed pair of 4 way speakers with a high sensitivity, very flat frequency response, and excellent phase performance.  Midrange to die for. 

But in general my suggestion is less than 10 watts in an SET, and the best deisnged high sensitivity speakers you can find.

@hilde45 Yes, transformers are key to tube amp performance but now you are getting into tube amp selection.  The original question was about speaker selection.  BTW, the transformers for my new custom tube amp are hand wound in Bulgaria.  Most expensive component in the mix.

@richopp  Let me repeat myself. This is not a magnaplaner thread.

@richopp We got it. You're a magnaplaner man, through and through.  But I will mention that I was pursuing an electrostatic speaker system when I fell down the tube rabbit hole.  My second system is still Martin Logan CLS.  It wasn't until I found tubes that I was able to exceed the clarity and definition that the electrostatic speaker gives you.  Not bashing your speakers but pointing out that there are other options.  BTW, this is not a magnaplaner thread.
