Riehl Copper solder from Starsound, has given me the best sound. NO LEAD..LEAD free highs. This formula is an original not just a re-label! I have 2 sets of cables both assembled by the same tech. One set with silver based solder the other with Riehl copper based solder. The Riehl based cables gave a much cleaner and more focused presentation along with more articulate mid and upper bass. The prescence of lead makes the others a no brainer!!!
