Update: I experimented biamping with pro-audio Y-cables ordered online, but these weren't transparent enough to keep in the system. I hated the thought of compromising my reference interconnects.
Then I saw this thread and learned about the hardwired XLR splitter-adapters made by Purist Audio Design. A truly "sui generis" product that has finally solved this problem for me. Not cheap, but worth it in a high-resolution system. Just give them some time to burn-in and they disappear sonically, let you keep using your current cables. Email Purist for details and photo if interested (this item wasn't listed on their website when I ordered).
A must-have for Levinson 38xx-series owners wanting to passively biamp in balanced mode!
