I don't know, but it sounds like something else is going on with your system. The higher end Supra Cables have received very good reviews. Some described their sound as being more open and less veiled, with very "tight bass".
Imaging with cable changes can be more focused or more diffuse. The imaging should not shift left to right because of a cable ( unless one is poorly terminated or damaged).
I have some 3.4S here which I bought for internal wiring of a speaker. I have not used it yet, but will do so soon on this project. I will get back with results. I also have Lessloss C-mark hook up wire, which has received very good customer feedback. I may end up using both; Supra for the mid-woofer and C-mark for the upper range.
Good luck!
