high-efficiency loudspeakers

I own Spatial Audio M2 Turbos - 94dB?  They're wonderful.

I have a pair of the new Spatial X2s on order.  92dB? Clayton Shaw and the world tell me they'll be wonderfuller.  Impatient?  Me?

I run the M2s with a PS Audio Sprout.  It's wonderful, too, and what? 33w/channel?  And a good 'nuff DAC, and Bluetooth.  Lively and fun with the M2s.

Twoleftears:  I promise to report back.  Unless I keel over from their wonderfulness...
