Just this month, after adding CruzeAUDIO Maestro outlets to my systems dedicated line and hearing very noticeable, immediate improvements in detail, imaging, bass control, blacker noise floor etc (which to my mind defied all logical explanation), I decided to take the plunge and see what a power cord upgrade could do for me, another thing that sounded like it shouldn’t have any effect on sound. Since the reviews I’d read for Maestro outlets mentioned a symbiotic relationship with Sablon Audio power cords that brought out the best in both (basically, 1 + 1 = 3), I purchased a Sablon Audio Corona power cord with the Oyaide C-004 upgrade to replace the stock made in Taiwan cord, running it from my Creek Destiny integrated amp directly into the Maestro outlet.
Wow! More MORE: better bass modulation, tighter definition of of all musical elements, finer pinpoint details and imaging. More clarity, without increasing brightness. So… my first foray into upgraded power cords was a rousing success, with the only downside being an urge to upgrade my current MIT speaker cables to the MIT Magnum M1.3 model to allow more of that beautiful sound out 😉
