Brodmann FS speakers with SET tube amp

Has anyone tried a tube amp on Brodmann acoustics speakers? 
Here are the specs, not sure how to interpret this data. Is this an easy load? 
I have a Mastersound compact 845 tube amp, which makes 30W
Mostly classical piano, violin, symphony, concertos..
Any other speaker recommendations  that would match this amp and my choice of music? 

  • Frequency Range: 55 - 20,000 Hz ±3 dB
  • Acoustic Crossover: 130 Hz (4.5 dB/oct)
  • Electronic Crossover: 2.0 kHz (6 dB/oct)
  • Operational Output: 1.9 Watt for 91 dB/m
  • Nominal Load: 40 Watt
  • Music Load: 80 Watt
  • Nominal Impedance: 8 Ohm

What does the impedance curve of the Brodmann speaker look like? Does it have peaks and valleys? What is the output impedance of your Mastersound tube amp? If it is over 1 ohm then it will interact with any speaker having a non-flat impedance curve. The result will be a non-flat frequency response from the amp/speaker combination. Hardly what can be called "accurate" sound quality! Ohm's Law rules here!
Get a pair of LS3/5A's! Either new or used! The BEST small speaker! Read Art Dudley's review of three versions in the latest Stereophile. They are outstanding with Classical works! I have a pair!
I would not think about LS 3/5a’s with a SET amp the LS’s need lots of power as they are not very efficient.

that seems, to me, a strange way to list spec's for those speakers. really wish manufacturers could stick to a standard spec measurements and not something that makes their speaker look better then it is. 
Bingo! That’s the problem with them in a nutshell. They’re very inefficient AND they don’t like a lot of power. What works best is modest power tube electronics. All around great speaker. Except for the dynamics. But nothing is perfect.
How did you deduce they’re inefficient? I’m still not clear how to interpret those specs. And how can a speaker “not like” a lot of poweR? If they’re 8ohm and 91db, that’s pretty efficient, unless I’m missing something.
