Digital Cable: To balance or not to ?

Here is the skinny as it has been explained to me by someone much smarter than both of us.If you are not balanced all the way too; and including the amp,all dig cables sound better single ended.

I have a SFT-1 and SFD-2 Mk II running balanced out to a Line 3 and Krell KSA200S (balalnced all the way) I have coaxial, AT&T glass, and now the balanced (using Alpha Core Perl silver balanced interconnects including as the digital cable. The balanced interconnect was the last of the balanced interconnects I got because I didn't think it would make any difference. I was astounded at the difference. I heard a big improvement from coax to glass, but from glass to balanced brought everything into focus and improved high frequency clarity, less grain, and more harmonic smoothness. Bottom end has more authority also.
