Based on your other thread you posted (you system is listed below) you should consider upgrading your CJ PV10a preamp. Upgrading to a placette, CJ Premier 14, CJ 17,or some other high end preamp will really suddenly open up the soundstage depth and width. You haven't even heard the true potential of your Super cables.
"My components consist of a Levinson 334, CJ PV10A, and Meridian 507 CD all plugged into Transparent's PI4. My speaker of choice is the Canton Ergo 900. I currently use Transparent Super XL speaker cable and a Powerlink Super cord on the amp"

I've tried 10k source in my system and instead upgraded to the next level Transparent cable( which cost more than my front end) and it was a bigger improvement in my system (of course both the upgrades were awesome but$$$$)
