Oops I mean DIY....
In your case,
20 AWG X 2 = 17 total AWG
17 AWG would give you damping factor of 79 for 6 ft ( assuming your nominal R for your speakers is 6 Ohm )
To do it right, your'll need to make 13 total AWG cable to get 200 DF.
For 8 Ohm speakers, I ususally assume 4 Ohm nominal load.
If this is the case, you'll need to make 11 AWG speaker cables.
I've achieved excellent result based on the calculation.
I can't say about your setup, but in my and all my friend's setup, my version of cable sounded as good as some XYZ brand speaker cables that costs over $3000 a pair.
Keep in mind,
Size of strands, number of strands, and geometry of cable do make big difference.
Since then, we have yet to find something better then my version of cable.
It is time comsuming but it is well worth it at the end.
Good luck
