Let's get back to a practical discussion of does it make a difference. I moved from unbalanced to balanced ICs with my C-500 (congrats on you purchase, BTW). My run is only 1-meter, but the CD/SACD player and Rowland are only an inch apart from one another in a relatively congested cabinet. I figured with all the potential for RFI and EFI with speaker cables crossing and ICs running every which way, why take a change? I use Analysis Plus Solo Crystal Oval.
Could I hear a difference? No. I suspect that the C-500's operation in DC mode has much to do with that. My initial impression, with unbalanced ICs, was of absolute background silence. That silence got no more absolute when I went to balanced ICs. If you change brands of ICs you'll hear it with the Rowland. If RFI is relatively low in your area and around you audio equipment, then you're not as likely to benefit.
