Indeed they are high value amplifiers Charles. Unfortunately they are a bit too large and heavy and I would be inclined more towards mono blocks of more managable size if I were to consider an SET. I have an audio buddy with a Mastersound integrated 845 SET with 2 845s per channel, which I've listened to many times. It weighs in the neighborhood of 130 lbs and puts out about 35 watts, a real beast. As I have previously stated, as much as I love the wonderful things that SETs do so well I do note their limitations, at least for me and in the set-ups I've heard. Like Mapman said it would probably take a very large full range efficient system to realize the potential, particularly in the bass but it seems you have the right formula with your speaker choice and amps. Though an SET might work satisfactorly for some in a main system for my musical taste and listening biases, I'm not so certain, at least with the Decapos. I would have to go in a different direction. As it stands now I have no desire or intention to do so but would just love to hear, maybe I would change my mind. As things stand now I am VERY satisfied, but one never knows what turns are in store in the future.
