Speaker for 300b amp?

Volti, Fleetwood, Charney, DeVore, Klipsch.

I am not sure about Tannoy or Fyne. In all case a sub will be a great combo

I needed speakers designed for corner placement, and went with the Charney Maestro with the Voxativ AC 2.6 driver, and I have used both WE and Takatsuki 300bs with them. The alternative for me would be Audio Note speakers, but I have been really happy with the Charneys. 8 watts is more than enough to drive them well above the volumes I play music at.

I guess my set up is a little out of left field but I'm running the Evolution Acoustic Micro One speakers with my Finale 300b evo and it's does just fine. The speakers are 88db efficient and I would go any lower. I had a pair of PS Audio FR5 that didn't work at all, but they're one of the least efficient speakers on the planet (83db) so I wasn't surprised. 

Also running an MQ30, but with Klipsch LaScala's.  A great combo

This seems a little backwards to me. Cart before the horse thing. Speakers have by far, the most effect in the reproduction chain.

Makes far more sense to buy speakers you love and then search for suitable amplification.
