My experience with Wilson has taught me that these speakers can be just as musical as anything else on the market.
I find it intriguing that others are so quick to judge the speakers without taking the rest of the system into consideration. Most speakers can be made to sound clinical or musical based on synergy or lack thereof with the downstream components. The room is also a huge factor, if not one of the most important.
I can attest that had I only listened to my speakers in one particular setting, I probably never would have bought them. Listening to them in a multitude of setups and talking to others with similar components as mine made all the difference. I can change my system's flavor with a few tube rolls and a swap of some cables which I think is simply great.
As a former owner of Bryston and a recent owner of Wilson speakers, I think they could make a nice combo. Hardly fair to use a broad brush stroke to paint a picture of either.
