Need advice on rich sounding cables

Spending $4K on speaker cables to make an $18K pair of speakers sound better seems a bit lopsided. Why not trade up to a better speaker or a tube amp or preamp before spending that kind of money on 16 feet of wire?

I picked up the Snake River signature that was being sold on Audiogon second hand, was advertised here at $1250 for a 3 meter biwire pair.

Great price.

will let you all know how it goes!

If you are going to demo cables, I would add Fusion Audio cables to your list, which are known for their midrange "liquidity". I found their Enchanter power cord to add some warmth to my Pass Labs amp, while preserving frequency extension. Cheaper SC options that play above their price point by a good margin are Clear Day Double Shotguns ($500), which I use, and Triode Wire Labs ($700). All offer generous, no hassle return privileges. The Cable Co is great, but their 5% charge per cable is money down the drain if you don't end up buying from them.

stealth is nice but wrong price for performance try calling Robert Lee at Acoustic Zen he is a great guy with a great balanced product that you can get what you need with your budget intact .
The kubala I heard seemed little tubby and closed down to me,tara was thinner causing wrong timbre but great product.
just my 2 cents
