Thanks for the update! Sounds promising! Enjoy the evening of great listening and music!There do seem to be favorable differences by adding the dual run connections. Listened to one track tonight, then removed the second cable, and then listened again. The musical nuances are better, more natural and fleshed out using the dual cable setup.
Now, the final test, put the cables back, but this time, make the dual pair, a braided dual pair by twisting the two cables together. Just did that and plugged it back in. Will be listening to that configuration for the rest of the night.
