I definitely enjoyed shopping at the Boston store on Newbury St. Seemed more like a family run business and I believe it's an independent store. The staff were friendly not just to the customers but to each other which made everything more pleasant. The pleasantries ultimately resulted in a couple sales while I was there last year. I particularly enjoyed their integration of other nonB&O (can't remember if it was lumitron?) systems which allowed you to use the beo4 and beo5 with lighting and other systems that are not sold here in Korea. After checking, I found that the voltage wasn't the same as here so they coulnd't be used, but hope to find such products at a differnet B&O location with same voltage. So far, no luck. :) Much different than the service on (edited: and removed store locations as I don't want to trashtalk stores) where I felt like, "you no buy, you leave."
I also recommend the one on Greene St. in Soho (I think that's the address). The ambiance and service there was nice. The one in Dallas, TX showed true southern hospitality.
For me, part of collecting and using B&O is not just the experience of owning and using high quality products but also the entire shopping experience, remembering what it was that sparked the purchase (whether a friendly gesture, a nice chat with a knowledgeable salesman, an unbelievable CD or just plain awesomeness in the product or product layout) and when sales or customer service staff are pleasant it makes the entire journey all the more rewarding. just my 2 cents.
