Mcondon,
Gabriel cable is excellent but did not own the Gold version. If you like music to sound rounded, warm, and involving, Gabriel is a no brainer.
The KCI is also an excellent cable. If you like music to have the same warmth but more speed and pace, its a no brainer.
If you want a little of both signatures, go with Grover H. It can be warm, fast, dynamic and bright sometimes. Hey, why hide what the engineer did on the recording.
Synergistic Research I have never owned. In nutshell, if you want some of the traits but don't want to spend the cash, go with Grover's IC.
None of these cables should give you a headache.
Got it then get it.
