i own 4 z-sleeves. while i find the product to be sonically beneficial--changing the tonal balance away from emphasis upon the treble, i would change my cable before buying z-sleeves.
one cannot predict which product--an interconnect or z-sleeve will have a greater affect, but intuitively it would seem that you could select an interconnect which could alter the sound to a degree which would exceed the changes accruing from placing a z sleeve over your current cable.
