Sure, that will work. I used stranded wire, but solid wire will work, too. The most important attribute for grounding applications is impedance, so any quality or design that will reduce impedance will be beneficial. Obviously, larger gauge will have lower impedance than a smaller gauge wire. This is why the Alpha cables sound better than the Venom/Delta and why Omega sounds better than Alpha (though the CMode filter helps, too.) The Shunyata ground cables are stranded, not solid wire, FWIW.Solid wire Stephen?
