KLEI plugs are the best sounding in my experience vs all the big dollar stuff I have tried. Great product line. I use them for all my builds. I never thought they were pure silver and glad they are not.
KLE Innovations Technical Paper
I've seen that a number of members have argued about the false "pure silver" and implied "solid silver" advertising that originally came from KLE Innovations in relation to their Harmony RCAs. The technical paper they've recently released for the RCAs no longer refers to pure silver. It seems to still fudge about whether they are silver-plated copper, but at least the pretense to being pure silver is no longer there. With all the forceful advertising that a couple of members were been doing for this company and the push back they got from other members - well, this looks like a small victory for some truth in the advertising from Audiogon.
