Which direction do you, the fine members of the Audiogon community, face when listening to their system? Regarding myself, the answer is north for the main system, east for the second system.
North for main and south for second. But never at the same time.

Everything's better to the North, read Scientology's book of wisdom, your in harmony with the earths rotational axis.
And an amp should be rotated so when you put your new $150+ fuse into it, the head of the fuse (amperage stamped end) should point North.

George your North is our south, therefore I'm gonna with EAST.

Proper chakra alignment, all powerful in stereo harmony.. 

It's also where the electrical outlets are..  Geezzzz!!!
I have never heard of this tweak. Do I need a clock in the room?
