I'm using the reference speaker cables bi-wired and the balanced Xshadow silver interconnects. ...just to let everyone know what I found in the break-in of these cables.....As they break in...they get grainy, fuzzy and crappy.... BE PATIENT> Actually, I found after break-in, they sounded the instant I installed them when they were new (for the first few minutes). They are now (again) very fast, detailed, fulsome in the low end, big soundstage...etc.,etc.
