You don't...unless you are asking to do so and then do it very lightly.

A few of years ago, I was visiting an aquainance that could not stop stating that his stereo was the best around. At that time he had a 60's vintage Pioneer amp and a pair of low price three way (10" woofer) speakers. I went along with him.

A little while later he was at my place and we had time to listen to a few tunes on my system, at the time a simple Luxman amp (hybrid) and a better Energy stand mounted monitors (6" woofer). The experience must have an effect on him for he upgraded his system to the point where all of us would drool at the sight.

Educate, do not critize.
