Not a sensible question OP.
Most people accept that interconnect and speaker cable changes can have effects on the sound. These effects arise mainly because of the interaction of the cables with the active components they are connecting rather than by the attributes of the cables themselves.
Further, each of us favours a different kind of sound.
So it is useless and damaging to take recommendations as to which are the 'best' cables for every system and every listener. You are very likely to be disappointed.
The only way forward is to listen to a lot of different cables in your system and choose the ones that sound best to you.
A dealer or widely experienced audiophile can help by using experience of different cables in different systems to narrow down your choice by eliminating combinations he knows are unlikely to be synergistic.
