Cables for an MBL Reference system?

Does anybody out there have any real life exp. or suggestions to maximize an MBL Reference rig?(101e's,6010d,1621a,1611f,9008a's).
I love the Radialstrahlers and probably never go back to a box speaker again, they just do magic to live recordings.
With all of the accolades that the 6010d pre has gotten, I wonder if the NOT truly balanced mode may be hurting my case, but many of my source recordings need it.
I listen to mostly live, older source material(GD, Allmans, NRPS and other acoustic/bluegrass/jamband music and/or female vocal stuff(Natalie, Kraus/Jewel etc).
I've been swaping out different cables for a few years and am stuck in the world of compromise.
Tara's don't cut it(too dark) without going to the Zero/Omega's, just rediculious $$ for wire.
Wireworlds(as recommended by MBL) have interesting coherency and great mid-upper end resolution, but don't cut it on the bottom end(Gold Eclipse 5 speaks), and their copper cables are too slow.
Has anybody tried any MIT, Kharma or any other high end stuff that may fit the bill.

Thanx in advance for any feedback.
