Odds are if you've had the 802d's awhile you're used to their tonal balance changing brands will probably sound off regardless of the brand.
That is total bullcrap. I’ve listened to B&Ws and Joseph Audio speakers in the same system, and the B&Ws sound broken next to the JAs. It’s not even close. My guess is B&W don’t know how to design a crossover, but that’s just my guess cause the rest of their parts are great. Once you hear JA speakers you’d NEVER buy B&W. Just my personal experience.
