Worth upgrading my cables?

I have long been a cable skeptic, but I’m now a believer. Like you, I had the Canare 4S11 Star Quad cables and felt they were a definite improvement over run-of the-mill basic speaker cable. But last year I tried the Nordost Ax Angel cable, which was on-sale at the time for 50% off, and the difference in sound quality between these two cables was vast. In comparison, the Star Quad was muddy, overly warm, colored, and offered much less detail. I didn’t realize how much detail and refinement I’d been missing until I made the switch. I purposefully try to avoid saying negative things about HiFi products I don’t like, and instead I prefer to highlight the positive experiences I have. In your case, I would highly recommend you try some different cables. I’m not recommending Nordost per se, and in fact, I’ve even considering an audition of some Kimber cables which might be even more neutral. But I sincerely believe you’ll reach a higher level of audio quality if you try some other options. Many companies have 30-day return policies if you don’t like a particular cable. Enjoy the journey!

@wester17 I agree.  GroverHuffman cables come with either a 30 or 60 day money back guarantee.  He can't produce them fast enough, so his one return in years was immediately resold.  His speaker cables are exquisite for the price and power cables are a necessity.  

Been curious about that product as well thyname...i would suggest maybe 12awg for your amps...seems from my experience lately that 14 awg is a tad light.Fwiw.
