Completely agree. At first I thought that silver cables may be too much of a good thing on the HD800 but based on my experience with them, the SWs perform exceedingly well with the HD800. The instrument separation, detail, transparency and smoothness goes up a notch and the bass is very controlled i.e. fast, tight and deep - almost stax like. Definitely an improvement over the stock cable (although the stock cable is very good). Highly recommended.
