No car... I walk. Office is only 2 miles from my place so it's only 30-32 minutes. Good for da body! AND, no plans for a car since I don't even have a driver's license (just a woofer's one).
With the amount of wires it would involve, I don't think I will A/B them!
I'll let you do that when your times come.
Could do a Left/Right channels test? Would that even make any sense? (that last question might actually be serious... I haven't decided yet).
