a magnolia home theater was recently opened in a bb in indy. the sales people seem like nice kids, but they have very little technical experience. i have also learned after shopping at various hi end audio/video dealers to trust absolutely nothing about what they have to say. do you own research, disagree w/ the sales person when he is inaccurate or incorrect, and i would never make a decision to buy based upon what a salesperson told you.
as for not bringing in the yamaha, it is my understanding that what magnolia sells, and the interplay between bb & magnolia is strickly limited by contract. better to think of them as 2 seperate stores under one roof. while i disagree with it, it's not the kid's fault, he was just doing his job. where he is at fault is downplaying a component which his store (magnolia) does not carry, primarily for the reason that his store does not carry it, and therefore it must be bad, or what his "high end" store carries is better. this is a very common sales tactic, as i have heard this in numerous stores.
