I don't understand people saying the W/P 8 is on the bright side... If anything it is rolled off gradually as it approaches 20KHz. When people say something like that, I tend to assume they haven't listened to the W/P8 in a decent environment and/or are basing their remarks on hearsay.
Now, if you truly want to hear a bright speaker, check out a B&W Diamond tweeter speaker. Personally, bright doesn't bother me, as I used to own the 802D which had excellent highs (attack and decay were extremely accurate, more so than anything else I've heard), though it was lacking in mid-bass and mid-range clarity. Those speakers were a bit bright, but I definitely wouldn't call the W/P 8 bright... If you like, you can look at my in-room response measurements in my System thread. There is an overall excellent gradual decline in the 1/6th octave in-room frequency response measurements (both in the singular measurement, which was at a lower "normal listening" volume for me, and the overlay, which was taken at a considerable increase in volume).
Given, it is a well designed room in terms of acoustic treatment (Rives Audio), but if you are spending ~$28,000+ on a speaker, you should at least be treating the 1st reflection points in your listening environment as well as randomly adding absorption and diffusion in order to kill slap echo. The only thing I can imagine that would spark a comment that the W/P8s are too bright, is listening to the W/P8s in a bad environment. In such a situation, only an excessively rolled off speaker will not sound bright...
