Yes -- works really well. With Nordost, I had used two separate runs of Blue Heaven to my speakers (i.e., double-biwired). BIG improvement over just using one run in all categories. Really, much better. Nordost itself had said using two runs of BH would approach the SPM's at a much more cost-effective price.
However, when I replaced the two runs of BH with Heimdall (one run), the Heimdall was much much better. The Heimdall's were really outstanding cables -- they are the first (and lease expensive) in the Nordost line to use the monofilament technology.
