A change in efficiency to the final sound

I have a p/p tube amp running a pair of 6Ca7's for about 30 watts per channel .
I have read here that p/p tube amps sound their best when they have to work a bit harder , as opposed to a SET amp that sounds best near idle .
My present speakers are claimed to be 92 db. eff.
If this amp is driving a pair of speakers rated at 85 db. efficiency , should it sound a bit better due to working a little harder or closer to its optimum level ?
Conversely , would the same amp sound a bit worse driving a more efficient speaker of 99 db. due to it working less hard or further away from its optimum level ?


Thank you

Also true is that the higher the speaker impedance, the lower the distortion.
Your speakers have 92dB sensitivity. That's good but more importantly is what is the nominal impedance? 
And no way to know how your amp will perform with 85dB speakers without knowing the impedance. And the impedance curve will help determine how the amp will respond to the load of said speakers.
