Bill, I just took my tube amp out of my system for a freshing; which means back in goes the Marantz. Now as far as comparing the differences, there are lots of that. Which one sounds better, they both sound really good. I think they both have thier own world. Now with k-horns I feel that the tube sound is a nice step up from SS. The SS with k-horns is really in your face kind of music, it sounds a little jamed together, does not seam to have the seperation that tubes do. With my HPM 1500's the SS is the only way to go, they are power hungry and require alot of watts. The louder you turn them the better they sound, not the case with the tubes and k-horns. It's all in what you like, and we are all a little different and hear a little different; so everyone is going to have an opinion. Is it right or wrong you have to decide that for yourself.
