@mwh777 Again, keeping an open mind can lead to sonic benefits.
I compared the supplied cable with a well broken in Raven Audio Sonequil PC.
I used Norah Jones Come Away With Me and Chick Corea Trilogy 2 as test material.
The vocals on on Don't Know Why, when she hits those powerful high notes, were much smoother - no doubt this means less distortion.
I listened to 6 other tracks on both albums and overall better clarity.
Best free tweak ever!
Happy I asked the question and thanks all for the feedback.
