"the 5A's (and the 3A Signatures as well) do not tend to "grab you by the throat" the way some speaker designs do"
Which is part of the reason they are such great speakers. Overly bright speakers grab you at the store but, fail to satisfy after you get them home and try to listen for hours. With the 5As hours of musical enjoyment pass and you still want more. They do require more setup expertise then most other speakers, however. Not because they are finicky but, you will find that wherever you set the controls at first they will require a second setup after about 200 hours and possibly a third adjustment at about 300 hours. A good Vandersteen dealer knows this and should offer to come to your house and set them up for you and let you know that he will be back to fine tune them after they are broken in. There is a possibility that your dealer's speakers weren't yet broken in. Also, it shouldn't be done by ear. He should have proper tools for the setup.
