wow. these cables are superb. right off i am getting a marked increase/clarity in bass and imaging is more precise. Certainly quieter background and more detail in high and mid, and enhanced soundstage. they really do all that mit suggests they will. i am surprised at the impact as i already felt pretty good about the sound. i expect them to perform better over the next few weeks as they settle in too. if any readers are shopping for power cables, i highly recommend auditioning these.
