IMHO,
If you already defined what sound you like from your system, a good neutral pair of speaker cables can only help you in terms of resolution, dynamic and imaging. Tonal quality shouldn't vary too much.
How do you define what's good enough for you is the difficult part done by critical listening.
I've auditioned from cheap radio shack, monster, lamp cord to expensive cables like audioquest, AZ, stealth UR, JPS, NBS Master, transparant MW Super...etc and then finally I made my own pure silver speaker cables and sold off everything else because it is better in my definition.
