Duelund 12AWG speaker wire sheathing

Parts Connexion.  They have various diameters.

I have a question on the use of sheathing.  

Yes it looks better and offers protection and possibly some damping.  And for a commercial product it is obligatory.

Some feel that sheathing changes the sound and, depending on the composition, could attract static charges (or something like that - I really don't know).

W/o sheathing, the heat shrink at intervals could provide some damping and keep the twist a little tighter.  

Any thoughts?  

I use 12 gauge Tempo Electric solid core silver. The only insulation is Teflon tubing, and they sound magnificent.

Regards,
Dan

I have used heat shrink at the ends and that's all I have needed. You can see my cables in virtual systems.  it's a loose twist on the Duelund since I didn't want any abrasion on the cloth wrap.

Use some 3/8 or 1/2" expendable flexible sleeving from Parts Express. Then use some shrink tubing on the ends.
