In Reply to: Validating use of TI-Shield on R-Cs (long) posted by bartc on December 2, 2007 at 20:14:18:
As per Chris and Alan, the earthing wire gauge does make a difference to the sound. As per Al and all of the above, these things do sweeten up further with a week or more of burn in. I"m really having fun here!I just started replacing my older R-Cs on AC cables with these Ti-Shielded newer versions and so far no adverse affects. I'll report on this later as I go along and they burn in.
Meantime, here's a crappy picture of the first one with the speaker cable grounds crudely tied in. (I realized after posting that this photo showed only 2 ground wires from the speaker/amp R-Cs and there are actually 3; one had come loose!) What you should see if you were here is: 3 ground wires coming from the speaker cable R-Cs (one is in a combined box at the amp end, rather than 2) wirenutted into 3 14 AWG ground wires from the AC R-C filter; a white PVC plumbing fitting as the base of an eventual housing; inside the fitting is a Ti-shield and microsorb strip surrounding the X rated R-C filter array of 3 C values as described previously. What you cannot see is that the TI is grounded into the same plug as the AC filter below with a 12 AWG ground wire, nor can you see the 3 prong plug at the bottom.
I like housing these things in the plumbing fittings for safety and aesthetics, but you don't really have to do that at all.
