   The technical arguments will be along shortly, but  there is for certain   
   a difference in the presentation of the sound. Connecting the loop   
   directly to the speaker seems to give a closer, tighter effect.   
   Connection to the outer winding shifts perspective to a different seat.   
      
   And a third way: un-ground the 0 ohm tap, and ground the 8 ohm tap.   
   Connect the speaker between them, and take tertiary feedback from the 16   
   ohm tap. The speaker is out of the loop, and perspective shifts again.   
      
   Preferences will vary.
