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

Hi Grinnell … yes I am still enjoying my Di Capo's .

Let's try this question a different way with this supposition ...

If I use this 30 watt p/p tube amp with two different speakers , one with 99db. efficiency and one with 86db. efficiency and all other characteristics being equal ,  would the amp have a different sound with each ? If so , how ?

Thank you all

I wanted to add , in the above supposition , that the volume for each speaker would be the same . This would mean that the amp would be 
barely idling on the 99db. speaker and turned up for the 85 db. speaker .

Would the resulting sound change due to how hard the amp is working 
or would the sound be the same regardless of how hard the amp has to work ?

Thanks again

kalali ;
I forgot  , in the post that you responded to , to add that the volume levels would be adjusted to be the same for both speaker tests .

Does that change your thinking ?

jrwaudio ;
   I would be interested in what you find out there . 

Now if I could hear from someone that has done it the other way two different speakers on the same amp , that would complete my information quest !

Thank you .
