[QUOTE=Marcocet;8038650]I've had the ncore 400 up for a while now, and they replaced a dual mono UcD700. They're a significant difference in the sound. The UcD sounded quite a bit more aggressive, and perhaps more impressive as well. The ncore is a lot more subtle. It sounds much more like class A amps I've used. /QUOTE]
That's a puzzler. I find nothing aggressive about the UcD. I look forward to more comments from other listeners.
