I added a set of Bryston T-10 active this January. What makes them "active" is the BAX-1 crossover and 6 channels of amplification.
To be honest my mid and high are via an ARC amp and I used Bryston 7BSST monos (700 watts) for the bass drivers- not the 1000 watt ARC amps they suggest.
My experience has been delightful although I think it's more abut the line array architecture of the speaker and the sophisticated crossover than the "active" idea. To me an active speaker should have the amp inside of it- like my subwoofer does.
I replaced my Model T speakers with these and I'm satisfied with my purchase. I don't want to use all the well-worn Audiophile superlatives to describe what I hear, but I have been pleased- smilingly each time I play them. I will say this: I also have a set of Maggie 3.7x for softer classical music that I use in another room. The Brystons slam like a thunder clap when you crank them- which the Maggies can't do.
Bottom line: The Model T-10 is a lot better. Is it $24,000 worth of speaker? Yes- under protest. I think all modern high-end gear is overpriced by 30%. I'd be giddy happy if they were 18K.
