I placed my order today and can't wait to see how the balanced XLR does in my system. In the past I have used RCA Single ended cables that came recommended highly such as Chimera, Jaden, and Pulsars. All great cables.
Interestingly enough, I ordered 2 pair tonight - one RCA, one XLR - to compare in my system.
While I'd love to compare an XLR version of my current favorite cable to the SE version I own, it isn't remotely economically feasibly. I haven't heard the cable I ordered tonight, but if it's anything like the cable two (3?) versions ago, I have little doubt I'll be able to accurately determine whether or not balanced cables improve the sound.
I still have certain reservations, but none are related to the cables themselves. They're excellent IMO, better than anything I've auditioned at 10x their price point.
