Choosing new cables

As far as IC's are concerned, I have tried Jade.  They were very good and as such, may be difficult to exceed, even now, without spending perhaps much more, or not, as the case may be.  Cost and auditioning results, rarely correlate. 

I did a fairly recent speaker cable comparison.  Based on their pricing and their uniqueness, I bought a pair of Silversmith Fidelium Speaker Cables to trial for 30-days. They’re competition were Nordost Tyr II’s and Iconoclast by Belden  — an OFE wire pair and a SPTPC wire pair.  Although the Fidelum's were less costly than the Belden's and much less than the Tyr's, I found the Fideliums (with my SoundLab speakers) to be more to my liking and returned the other two loaner pairs.

An in-home audition is mandatory, especially given your very good, but felt to be old cables.  Many dealers and manufacturers offer in-home trials.  And the Cable Company -- as has been mentioned herein -- is a good loaning source.  Cable auditioning isn't a task that I enjoy.  But it is a necessary one.  Good luck!   

After my above post, I recalled using the following website as a primer (if you will) for making cable selections for auditioning purposes:  Audio Bacon 

Obviously, like all reviews, the outcome is subject to the reviewer's ancillary equipment, room and their presentation tastes and preferences.  However, the question of where to begin the auditioning process is always a foremost one.  Thus, the more information that can be amassed and analyzed, the better.
