One detail to add is that the outlets used for my system have carbon fiber slabs cemented to the cover plates. These add a minor increment of improvement over the case with no cover plate. I confirmed this by making more filters for my other circuits after the reported test.
This test was conducted on a dedicated AC circuit that feeds a single Oyaide Ultimo SWO-GX+ outlet. The Wadia 861 is plugged into one outlet, and the filter into the other.
It is important to allow the R-C filters with TI-Shield to 'burn-in' for about a week. When I compared freshly-made filters to my existing setup, I found the 1 KVA transformer and some two-wire filters to be superior. However, after a week of exposure to the AC, the TI-Shield versions became more effective than any of the others. The burn-in can be done on any AC outlet.
