The electronic techs and music collectors at turntableneedles, agree, the SR125e cabling upgrade is an exceptional quality option to have. It's an atomic level improvement in copper that should give that extra edge in signal retention.
Black Is The Color Of Space
Grado Labs developed our proprietary SpaceBlack Polycarbonate to
absorb stray sonic vibrations. Those unwanted secondary impulses can
'muddy' the sound, and we're all about purity. The SR125e uses
ultra-high purity long crystal oxygen-free copper voice coil wire, and
an eight-conductor cable. That's scientific. Get onboard the SR125e if
you want space, you want black, and you want the only mud hitting your
ears to be Muddy Waters.
… the '125 is a neutral, detailed, and
warm sounding headphone overall, with extended frequency extremes, wide
dynamic range, and the ability to sound natural at a wide range of
volume levels. Based on my experience with the budget and
top-of-the-line Grado models, I remained convinced that the SR125
represents the greatest sound quality per dollar in the Grado range.

Grado's ability to combine lightness with extreme rigidity and
internal damping has been put to good use on the SR125e.
The SR125e features a state-of-the-art driver and cable design utilizing
UHPLC (Ultra-High Purity, Long Crystal) copper voice coil wire. With
the 8 conductor cable design you will notice outstanding control and
stability of the upper and lower range of the frequency spectrum, with
both supporting Grado's world renowned midrange. The Diaphragms are put
through a special de-stressing process in order to enhance inner detail.
The way the SR125e's new driver, cable and plastic housing move air and
react to sound vibrations are virtually unaffected by transient
distortions. Bass, midrange and treble are open and you will enjoy the
fine tonal spread and balance. The SR125e will produce a sound that is
pure Grado, with warm harmonic colors, rich full bodied vocals,
excellent dynamics, and an ultra-smooth top end.
