Not sure if your 803s are new or relatively new. I've read a number of comments from those who claimed these speakers sounded harsh/bright when new or relatively new, but once burned in this impression went away, and the sound became very listenable and satisfying. Otherwise, I did have the opportunity to audition several of my classical "test" lps on the current 803 Diamonds in an audio salon and found the entire experience extremely enjoyable. I heard absolutely no stridency or brightness whatsoever. I would be somewhat surprised if the tweeter in your 803 model(preceding the Diamond tweeter) sounded harsh after being broken in. Incidentally, the electronics used in my audition were by Ayre.
