Bob, I actually began with the Audioquest splitters. I found that the Audio Sensibility splitter cables were much better and they allowed me to hear the difference when I improved other things (eg a better power cable and further improved vibration control for my music server and mixing and matching ICs using the DS method). I found that the combination of a Teo Audio GC II and a Zenwave D4 on each leg was better than simply using two pairs of GC IIs, at least in my system. I am still breaking in the silver version of the Audio Sensibility splitter cables, but they already seem to be at another level higher again. Cheers.
