Dealer Bias: Do They Really Add Value?

Many posts refer questions to a "dealer you trust", "get advice from a qualified dealer" etc. Maybe I have lived in big cities for too long, but these posts strike me as very naive or possibly written by local dealers masquerading as members on this board. Do you really think that dealers aren't biased, often ill informed or motivated primarily by profit? I dont' want to take away from the sincere people and genuine enthusiasts in the business, but I can't even count the number of times a "reputable high end dealer" has suddenly decided that Levinson is actually better than Krell, or Burmester blows Audio Research away, or we started having problems with Martin Logan, Audio Research etc. only months after they were touting the very same brands as the best thing in the history of the universe. Brands of equipment that work well together are often not sold by the same dealer, or even in the same state. I don't know but it seems that hotly competing lines are rarely represented by the same dealer. I agree that we should reward and give business to dealers who genuinely provide an excellent service, build long term relationships, give good advice and really go the extra mile, but all too often dealers seem to whine about , a shrinking market, customers who don't appreciate their service and value added etc when they need to look in the mirror and ask how much value they really add. I go OUT OF MY WAY to give business to people who try to get to know me and really take care of me, but when I perceive a mediocre, biased, commodity service, I am more than happy to get my advice from all of you and shop for my electrostatics, exotic cables and monoblocks on the internet at the lowest possible price.
