Great company that is for sure. I don't have any of their amps yet but if they are anything like their preamps the're very good. I have their top preamp the C900 and it is one of the better preamps out there. But more than that the company is solid with the upmost integrity. They stand behind their products like no company I've ever seen. Customer service is the best, they will do what ever it takes to ensure customer satisfaction, what ever it takes. I also use the Martin Logan speakers.
