RCA analog cable choices

Without knowing what sound characteristics you’re looking for it’s tough to make a recommendation, but here are a couple worth a look and they offer trial periods, which is nice in your situation.  Morrow and Zavfino are some others in your price range with trial periods as well.  Not familiar with the Kimbers so no opinion there.  With your speakers I’d  shy away from silver or silver-plated interconnects as they might be a little bright sounding.  Hope this helps, and best of luck.

@soix Thanks for the suggestions. I will take a look at those. As for sound characteristics -- 

I listen to all types of music - streaming mostly - quboz. Ranges from jazz to elecronica to rock. So the sound I am looking for is something not fatiguing - I don't listen to it loud - as I don't have a separate media room like many - my wife and 8 yr old can only handle so much. 

Warm, luscious, but detailed, and accurate as my system can resolve given its inherent limitations.

I am looking to optimize and pull out all that my gear is capapble of producing.  B&W sound is fine with me - forward, detailed at the top, and great decent midrange voicing and decent low end. 

I haven't done the whole - chasing nirvana in my audio system - as I don't have the time or money to do the endless pursuit of perfection -- swapping out cables endlessly etc... and my listening space currently will never be ideal - 

So - what sound am I looking for? As I said - traditional b&w sound that they have made a name for themselves over the last 5 6 decades. 

I don't want anything too bright - still detail but not fatiguing like I said... warm, fast, sort of in your face, but laid back at times... just depends on what I am listening to... Diana Krall... laid back sexy and oooohhh... but if I am listening to Digweed or Tiesto or Megadeth... I want fast, great midrange and tight fast bass response... 

Hope that doesn't muddy the water too much.

Maybe give a look at Silnote Audio and Triode Wire Labs, both provide quality construction and nicely balanced sound to my ears

You will receive many recommended cable choices here.  It seems you want reliable, relatively economical, RCA analog cables that accurately transmit voltage signals between your equipment.  A good pro audio cable from a company such as Mogami, Belden, Canare, Gotham, and others should accomplish your goals. Pro audio type cables are typically designed to achieve neutrality, durability, flexibility, and resistance to interference. Beyond that, personal preference and money come into play.

Third party constructors such as Blue Jeans Cables, Worlds Best Audio Cables, and others supply customers with terminated bulk pro cables. I would look for a shielded twisted pair, foamed PE insulation, and reasonably good connectors.  I like the Gotham 10666/10561 GAC-2 UltraPro 110 Ohm Digital Audio Cable (link), for both digital and analog purposes.  However, if you cannot terminate them yourself, it may be easier to find offerings from Belden and Mogami in the USA.

Mogami 2549 ($25/pair, 6 ft) - low capacitance (23 PF/ft), neutral

Mogami 2965 / Neutrik connector ($30/pair, 5 ft) - low capacitance (17 PF/ft), 75 ohm, neutral, you could use it as a digital cable as well.

Veritas Fidelis ($350, 1.5m) - Smooth, slightly warm side of neutral

DH Labs Air Matrix ($500, 1.5m) - Neutral, more bass presence

* If you don’t need to use cable for tuning your system, try Mogami first.
