Cable recommendations for cary slp-98p & cary 120s

Jakecanada,
I agree with what's been said, you're happy with the silver Kimber, so why not stick with it? The quality of silver cables can certainly vary among brands. The better quality ones will provide excellent transparency and will preserve the natural warmth and tone of your tube components (as you've discovered). I'd stay on the same course if I were you. Many opinions on this frequently asked topic but I find good silver cables more natural than good copper cable.
Charles,

Jakecanada, check out Audio Sensibility’s Statement Silver interconnect. They are made with Ohno Continuous Cast (OCC) silver with a purity of 99.99998% (7N), terminated with Furutech and custom-made 303 Stainless Steel RCA barrels. Retail is only $399. They are a small company with excellent customer service and only use well known high quality materials/manufactures without the insane prices normally attributed to silver cables.

I changed out my Kimber Select series for these cables. No affiliation other than a happy customer.

BTW: A good way to audition cables, in your own system,
without having to buy outright, is The Cable Company's lending
library: (http://www.usedcable.com/) &
(http://thecableco.com/) Whatever you pay for an audition,
will be deducted from the price, should you decide to
purchase. Great people which which to deal, and you don't
have to depend on someone else's opinions/tastes/aural acuity.

I've had great luck with Goertz AG1 silver speaker cables and Sapphire interconnects in one of my systems.

P.S. I forgot to add I have Cary SLP98 plus Cary v12, 300SEI. Best with either of these systems.
