While I never recommend spending more than necessary on Cables, Belden and Canare are considered good brands that sell for a little more than the Monoprice mentioned above.
For the record, I use the Monoprice 12AWG in my system.
Some measurements indicate that some of the basic Belden product has slightly better properties.
Now... are they audible?
Not very likely. But... there are options if you want.
I agree and stress the point:
Do Not spend a lot on Cables. It really becomes more a point of Ownership Pride and Bling, getting fancier cables. So if you do want something sexy and expensive, cool. I would say do what
@gene does and buy Kimber Cables. No magic marketing claims, but you pay for beautiful and well made product.
Or you can build your own Cables, too. Some Monoprice or Belden 14/4 or 12/2, Cable Pants, Cable Sleeves, terminations of your choice... You can do them straight, braid them, whatever floats your boat.
