Yes I can hear a BIG difference in my system. FYI, I've owned many 6 figure systems using MIT and other brands over the years. I could afford to not be frugal:O) My current system, although very humble compared to the plethora of reference components that have graced my homes, is quite resolving. Check out the PM1 specs etc.. My source even specs up there with the Esoteric's of the world. But more to the point, cable IS ONLY WIRE...UNLESS YOU ADDRESS THE COMPONENT INTERFACE PROBLEMS AND SIGNAL TRANSMISSION ISSUES. MIT is THEE cable company who has substantial technology and research that do just that. BOTTOM LINE IS DON'T TRUST ME...TRUST YOUR EARS!!! A well designed product WILL BE efficacious when used on any level of componentry and will do so consistently. On any given system, putting in a commensurate MIT cable product vs (insert cable x's name here), will yield a more realistic auditory experience. That's what 30 day trials are for my dear fellows. Of course, not everyone savors re-creating the hallmarks of live music in their system as much as the next person. Therein lies the rub no? With every conventional cable comes unpredictability and standard aural phenomena. With MIT, you hear a compelling reproduction of the musical event intact, with correct tone, pitch, timbre, dynamics...all within a spacious, airy 3 dimensional soundfield. The difference isn't subtle...it's paradigm shifting. I know some people that don't even hold tone or dimensionality as important factors in stereo reproduction. I would consider such people ignorant and misguided.
