Thiel Owners

A cable note worth mentioning (again?) regards binding posts. Going back to the 2002 CS1.6, Thiel used gold plated brass binding posts with a big knurled knob. I could speculate about how that came to be, but I won't. I will say you can achieve considerable sonic improvement by removing the knob and using banana plugs.

The slightly opaque, clacky quality, especially noticeable on the high end will vanish. Easy, inexpensive, worthwhile.

A complication is the center hole being slightly undersized so all males plugs do not fit. I re-bore with a 4mm / 5/32" drill. I use the WBT-style angled, stackable, expanding male ends, and make contact in DeOxIT contact grease.

Much is often made of the large surface, high pressure connection of spades. My exploration led to examining field propagation along the wire run and its scrambling at a bulky binding post. A low bulk, straight connection does everything right, and an expanding plug makes good contact. Try it.

Feel free to mention Cabling as often as you wish. After all, Cabling,  is the forgotten/over-looked component. Absolutely vital to any System.

Happy Listening!

Tom,

I use the nude termination on my Morrow SP7 cables into the 3.7s. Also the same contact grease (on your recommendation).  Since the cable could slip out easily, I had to "secure" them in place with a wrapping of electrical tape. Still not optimum, but the sound in fabulous.

...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.
