i think ichigo is correct, it completely depends on how close you are with this friend. The only people that i would interject like you are saying, are some of the guys i served with in the military. After the purchase has been made, that can be a sticky situation, especially when a wife is involved...... Also, you need to consider, that they have probably been exposed to 10's of millions of dollars of advertising, think about how often you see a bose commercial? Do you think you can make an argument against that much advertising, without offending anyone?

Oh the A/B comparison, that could be interoperated as snobbery as well.

Thats about all i got bro.
