I earlier posted in this thread that when I put a braided shield over my I/C to remove hum it very negatively effected the sound. Since this time I have built the VH Audio DIY cable using #28 cotton insulated silver wire by Jupiter over a cotton stuffed Teflon tube. The sound was impressive (better than anything that I've heard up to $600 (my cap)) however it did hum with my Grado 3mV high o/p cartridge. So, after wrapping 3 layers of Teflon tape, I installed a soft flexible braided outer jacked which I then wrapped with Teflon tape. Following this I took kitchen aluminum foil cut into 3/4" strips joined together and completely wrapped the Teflon layer making sure that the foil did not contact the connector at either end. I then ran a small gauge plated copper wire from one end to the other over the foil making two turns over the 1M length. To one end of the wire I connected a 7" insulated wire with an alligator clip (half of a common electronics jumper wire). Over this I wrapped two more layers of Teflon and then applied the heat shrink over the connectors / cable ends with the insulated wire coming out of the back of the heat shrink.
Results: Zero hum, dead quiet black blackground to the music, no degradation in the sound quality whatsoever. (Aligator clip attaches to the preamp chassis.) Interestingly after burning the cable in on my burner for 24 hours I noticed a slight brassiness to the highs which I thought may be a characteristic of the silver but after a few albums it has gone away (yes I compared it to my old interconnects to be sure).

If you use MI or MM cartridges the capcitance of the cable can play a very large part.... - viridian 13:10:22 01/09/17 (1)
