The Six Shooter has proven superior,IMO to the Mcintosh C2200, Audio Research LS25MKII, Audible Illusions Modulus 3MA, and all the internal bypasses of every surround processors that I have tried. What's your experience? Would love to hear about pre-amps that beat it as well as those they have not. My intent is to get an idea of how much you really have to spend to get better performance?
