In Reply to: RCA Interconnect wiring options question posted by Davy on March 16, 2007 at 11:55:55:
Carefully strip off the outer jacket, shield foil, and and any internal binding. Remove the drain wire. Make a pair of interconnects using just the twisted pair... I've made cables like this before, and they can sound very good. As always, YMMV!
Follow Ups:
from 5 Easy Pieces. Why not just use some Teflon cat 5 wire? I have found that very low capacitance cables work best for phono IC's. If you have to shield, keep the shield as far from the IC as possible. I found that about 1/2 inch minimum is necessary for no increase in C.
He could certainly try the cat5 wire... didn't know whether he had access to any. I have tried the "stripped" twisted pair from high quality mic cable, and had good results.
Many thanks for the advice,
Sound a bit tricky but interesting (stripping everything off and using the two insulated inner wires only.) But what is the difference between this and using the cable with the casing etc, connecting the two insulated wires to RCA pin and RCA collar respectively and cutting the drain wire very close to the main plastic insulation housing and taping to make sure it doesn't contact the RCA plug at all? Does having the drain wire and plastic shield present put not connected harm anything? Am I missing something?!
floating shield.My practice is to ground the shield at the load end, not the source end, of all cables.
In this case, Duster and I agree. The preamp is the place where the whole audio system audio ground should be referenced.
I meant to direct Davy to ping you, but typed Abe Collins instead of Al Sekela! Whoops! Anyhoo... cool that you jumped in here. I was assuming that he was trying to make garden-variety line level interconnects. If I had known this was a TT to preamp or step-up xformer setup, I would not have offered the same advice! I stand by my recommendation to try unshielded twisted pair for line level, although it may not be the right configuration for everyone.
Sorry SF Tech,
Should have originally explained I wanted to make two different cables. Thats partly why I was getting confused with all the conflicting advice. It is becoming clearer now!!
