Haha if it was you who installed the Bryston and all the cables etc then, given your advice to him to buy a SET ... I would suspect you simply configured it all wrong. ;-))
I've been running my Maggies 3-way active for over 15 years and not a single listener has ever said they sound congested!
I presume you just replaced the external passive XO boxes with the Bryston? What amps did you use after Bryston - on the bass panels and on the mids & ribbons? Did you feed the LP output of the Bryston to the bass amp and the HP output to the mid+ribbon amp?

I ran a Maggie Tympani using an Audio Research Corporation (active, tubed) EC-2A X-O and ARC tubed amplifiers over *thirty* years ago c/o any problem.
So, Norman ... you would agree that the OP must've screwed up his active implementation, somehow?
I personally think he probably fed the LP output from the XO to his mids+tweeters and the HP output to his bass panels. ;-)) (Which would certainly sound very weird!)

I most definitely agree that the OP could have "screwed up". I indicated that in an earlier post when I wrote about the possibility of "human error" being involved or a fault in his Bryston X-O. Being considerate of his ability to correctly wire up his system, I wrote it likely that X-O was at fault.
Now that I think back to my earliest experience bi-amping a Tympani (using that ARC EC-2A X-O), it's more like 40 years since I did that. I recall concluding back then, 'what's the big fuss about bi-amping'? Nearly most of the time (or perhaps all of the time) I couldn't hear 'any day and night' difference between the ordinary vs bi-amped configuration. If a were put to a 'blind' test, considering the time required to re-wire the system any difference in its sound would have been gone.
The First Watt B4 is a better active x/o for use with Maggies than is the Bryston. The B4 offers 4th order-24dB/octave capability, and frequency settings in 25Hz increments (from 25Hz into the 1250Hz area). Marchand can make cards to even finer graduations, but they contain opamps (if that bothers you ;-).
