How many audiophiles do you need to change a lightbulb?

Four:

One to purchase multiple brands, shades and wattages of bulbs and administer the double blind testing.

Three to give their opinions.

If you have to ask the question, you are NOT a real audiophile! Besides, I’m still admiring the  velvet gloves and high heels of the wife of noble1001!

^^^^^^^
Yeah, that visual image is still in my mind too.

Changing a light bulb is so old paradigm. As everyone ought to know by now you need four light bulbs distributed asymmetrically around the room.

No doubt that an audiophile will volunteer his or her opinion about a change and many will offer a different change as an alternative, but I must ask, does the light bulb actually need changing or is there some other issue upstream causing the problem?
