I use a very similar configuration, very high purity copper, fine strands to mono blocks on a very short run 3 or 4 feet. I’m actually using quad wire from the BHKs 300 amps dual binding posts. (Mid/hi, bass, super tweeters and subs- each with its own run) I’ve run the wire various ways... bare, rapped in seran wrap, tubes , etc.
The set up sounds good -especially for a DIY situation.
But surprisingly, I recently put in the new Belden iconoclast speaker cables to try (I’m signing up as a dealer). The shocking thing is that the speakers were actually louder with these very low impedance cables than bare high purity copper.
The iconoclasts come with measurements of each cable created. I know Belden isn’t known in high end circles just yet, but Galen Garies, an engineer at Belden Is an audiophile and convinced them to release his high end design based on measurable science. The white papers are impressive as is the sound and for a very reasonable cost compared with other high end designs.
Anyone that wants to hear these cables in their own system, PM me.... I’d love to get some feedback.
