My experience with them is somewhat different. I have not found the staff to be knowledgeable, and apt to try to sell you magical wires that you don't need. Of course, if you are a true believer in magical wires, then you may call such things evidence of "knowledgeable" staff. I call it a con job. There is also a level of snootiness that is common among stores that sell more expensive equipment. Of course, some like such treatment, as I am reminded of a "New York" deli (not located in New York), in which the staff were rude to the customers. I remember one patron liked such treatment, as he felt it made an "authentic" New York experience. To each his own.
