I haven't heard the Acoustic Zen MC2, but I've had AZ interconnects and cables for over a decade and they do extremely well with the highs. Since there is a "house sound" to AZ cables I'd think the MC2 would follow suit. To be more specific, I'm a drummer and am very sensitive to equipment or cables that turn cymbals into sizzle/hash or emphasize sticking over tonality. My AZ cables do an excellent job of capturing not only the clean sticking/dynamics of a cymbal but also its tonality and weight, which is something I don't hear often in cables. So FWIW, I think trying a used MC2 could be a good idea given your preferences. Best of luck.
