I had one of the later Soundcraftsman (1990ish) amplifiers after they had been aquired be MTX. I used it with a pair of K-horns and it got the job done. Very Bryston like in its performance without the finesse of the more expensive Bryston amps. What that means is a ton of power with great impact, but lacking subtlety on the top end. Both the Klipschorns and Soundcraftsman amp/preamp have moved on, only one of them I wish I had back on an almost daily basis! Jerrod
