Well, I don't know if 'muddy' is the correct term, or the most common one to describe the Quest-z, but, there is something just not there to me. My JBL 240Ti's or AR9's sound much better at those frewquencies. But, the Quest's are not in the same room, or house for that matter. At what price could you folks 'live' with the Quest-z's I wonder ?
