Based on what you said about the Cardas NR & the MIT Mag 3, I'd look at Acoustic Zen's best copper I.C.. That ain't based on the hardware as you asked, but it is based upon playing with the same three cables in different locations in my system.
FWIW, seems like the NR is a good cable to keep in your tool box, they seem to have a way of eventually working their way back somewhere in your system over time. FWIW & IMHO & Your milage may vary.
Oh, the head cheese at AZ says his silver I.C. is a good one that doesn't bite hard on top, but I've never heard it and have never ended up liking a silver ic.
Good Luck!
