If you really have no frame of reference or starting point consider getting some inexpensive yet very good quality cabling from Blue Jeans. They sell Canare 4s11 and Belden 10ga cable which will not only sound quite good (neutral), but can serve as something to compare, and gauge the value of, more expensive cable should you wish to explore further. The Canare sell for $1.35 a foot and the Belden for $1 a foot. You can buy in bulk and terminate it yourself and save a few more bucks.
