Like chrissain suggested, try straight without shield first. If it's too bright sounding, try braiding. I have found that will calm down the harsh/brightness.
To Shield or Not to shield-That is the question!!!
I am building a couple of 4 meter balanced cables from the Duelund 20 gauge wire- I am getting conflicting advice from different folks "In The business"" as to whether to shield or not- A few has said the cables sound much better without a shield- any thoughts would be appreciated-
