If this is a mic cable, I think this is the model I used around 4 or 5 years ago. But I remember it to be GY and not IY. Well, if this is it, Highs are extended, mids and bass have good body. Not a bad cable on the right equipment. Not so good if you're into imaging and dynamics. I find it to be warm. With warm, I don't mean rolled off.
Hope this helps.
