WBT connector upgrade


I�m about to order a 4m length of Kimber Hero interconnects with RCA connectors. The standard connector on the Hero is the WBT-0144, but you can upgrade to the WBT-0108 for about $70. Need some input as to whether the upgrade is worth the extra money. The interconnects will be used between an Audio Research SP-9 and Classic 60 driving Vandersteen 3A Signatures. Thanks!

Definitely, I've had both on KCAG and KCTG, I noticed improvements dynamically, but even more in the midrange, more realistic.
Just my humble opinion, I never liked WBT connectors. I much prefer the Cardas line of connectors.
