4 ohm tap vs 8 ohm tap

I have read reports about using the 4 ohm tap regardless of what the ohm rating for your speakers are. Right at this moment (who knows how long) I am using Meadowlark Shearwater speakers with Rogue Magnum 120 amps.
What would the audible difference be? And could I cause any damage to either products by running the Meadowlarks which are rated for 8 ohm with the 4 ohm tap?
Thanks, Scott

Aroc,

Alraul is correct - the full primary winding is always seen
by the output tubes.

The different taps are on the secondary side of the the
transformer with higher tap impedance having more windings.

Hence the 4 ohm tap will have the fewest windings of the
set of 4, 8, and 16 ohm taps.

Alraul,

I do end my post with my qualifications - and I get a lot
of flak for doing so.

The qualifications work as a double-edged sword.

The fact that I put "Physicist" after my name says that I
do have a special expertise in Physics. It also says that
I have absolutely no special qualifications in anything else.
