I think you'll have to give us some idea of a budget range. For example, Calvin has proposed a $4000 set of speaker cables (Shunyata Alpha v2). While those are undoubtedly fine cables, they may be more than you're willing to spend, or they may be not quite as high-end as you want. It might also be helpful if you could list some of your electronics and speakers, as cables are often produce different results with different gear.
My Quist is to, have so little coloration of the sound as it can be ( live like feeling sound ), when it come to cables. The coloration stands my Valve Equipment.
