Should there only be one company making gear?

would you want one choice of shirt to wear?
One band on CD/LP to listen to?
One kind of car to drive?
One nationality?
this thread is 'different'

Sure, and that would be the same day we all agree on the best music, women (sorry, Elizabeth!), cars, vacation sites, vodka, tequila, and best boxer of all time. Easy enough, don't you think?

ONE item that is part of the reproducing chain that we just accept as is AIR.
Free, and comes in several trillion different scents, but basically the same.
Get yours now(
the sound waves gotta get to your ear...)

its phillips' and sony's world, the rest rest of us just live in it.

My motivation in asking this was due to the RAGE expressed by certain people, even some who have posted on this thread, that hate anyone who does not have, and appreciate the same gear they have.

In these days of political correctness all this hostility cannot be allowed. It amazes me the venom that some people are willing to spew on those with other likes and dislikes. If there were no choices there would be no controversy, and we could all get along.

Does it make any sense for people to be hostile toward one another because of their choices of stereo gear?
