I was looking for a high quality Y connector and the options seemed to be solid Y splitters, which effectively mean you have to buy 3 interconnects for each channel plus the solid Y, or getting one built. In my quest, however, audioelectronicsupply.com said they can get a Kimber Kable Y connector with 2 6" male leads and a female RCA end for a fairly reasonable price. Because WBT doesn't make cable terminated female RCA connectors, they end up using a chassis mount RCA and heat shrink tubing. Apparently it isn't pretty, but you can get one built out of KCAG if you want.
I gather from my research at some point that there is some marginal benefit to "splitting" at the amp end rather than right out of the pre-amp.
Best of luck.
