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.
I face my system and according to my phone that's almost due south but a little bit east.
I face East with the living room system(s).

I face North when on the iMac/puter.

I face East when when watching TV (our only TV is @ the foot of our bed).

I face creepy people, like MC, mostly here on A’gon.

Facing away from the system.  Music hit the ears faster and blacker blacks, much bigger soundstage.

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!!!
No clock needed, compass maybe. You should follow Feng Shui principles 😉 for best harmony.

The way science works, if you want to know the air speed velocity you perform experiments. All the science and logic you need to be an audiophile:
