...sound is...

When you say 'nude termination' I take it to mean the cable is self-terminated with no additional hardware. Good move. But now to the speaker input terminals. Whenever there is a cross-sectional excess of conductor in the signal path, eddy currents are induced along with other forms of non-linear flow. Those induced reactive fields present erratic impedance to the input signal. I suggest you put some straight or 45° banana plugs on the ends of your SP7s and fit them to the terminal center holes. Set the nut aside. (The actual post is OK.) Compare. Report.

Tom,

Yes, cable is self-terminated with no additional hardware. Nude is what Morrow calls them!

But re the banana plugs -- I could do that. Do you have recommendations regarding brands and/or materials?

The clones I described above are gold plated brass from parts express. Genuine WBT multiplies the price. 

Tom Thiel you have sparked a light ball in my brain. Eddy currents are another descriptive term that falls into the file cabinet of interfering energy. Same goes for shear wave interference and boundary interference. Right angles are a simple eyeball example..to be continued.. TomD
