Bear Labs compared to Say -Acoustic Zen Silver ???

I have been told that these cables could be Dragon Slayers.
I presently own Acoustic Zen Silver, Electraglide Signature,
Synergistic Resolution Mk11, and JPS 2 Interconnects.
My preference is the Electraglide Signature.
Is the Bear Labs worth a purchase to compete with my present selection ???
Thanks,
Ken
