All you guys that are passively bi-amping, what are you using as a Y-adaptor? I too would like to passively bi-amp my speakers but I shudder at the thought of placing a Radio Shack (or derivative thereof) Y-adaptor connecting my Audioquest Opals between the pre and the amp for each channel - seems like it would defeat the purpose of purchasing good interconnects. Anyone know of a good Y-adaptor? - What it is and where to get it? The "best" I have seen so far is Monster Cable (the low-end stuff found at Best Buy and the like) Thanks, guys!
