The informative review of the Empirical Audio Clarity 7 speaker cables at Positive Feedback is very interesting and verifies other reports I have read regarding their performance. The current review is significant for me because it favorably compares them to cables I know are excellent. Definitely worth an audition.
The Gecko jumpers would need to be terminated with Z plugs or bananas, change the connectors on the speakers, or use adapters which is an added connection. I'll probably change the connectors on my XO's and speakers eventually to spade type during the next phase of XO upgrade. I have already eliminated the extra connections for biwiring on the XO box, bypassing the tweeter attenuator and fuses on the speaker with very worthwhile results.
