At the risk of sounding self-promoting I am the distributor for a very nice line of connectors made by Puresonic. These too have the lightweight polymer "chassis". All of the connectors have a very low mass with a black anodized barrel that is machined from solid aluminum. These can also be purchased with a satin silver finished brass body. Puresonic makes three different types of RCA connectors for different wire configurations. The Puresonic GAP RCA plug has a single larger ground tab and works perfectly with coaxial cables. The Puresonic "BALANCE" is most like the Eichmann product in that it has only two small connections points, perfect for paired wires. The third connector from Puresonic is called the "MULTI CONTACT", it has two tabs and the hookup for the signal. One tab is for the shield, one for the return, and one for the signal. The shield and return tabs are electrically separated until they are actually connected to the RCA jack. All are patented and make use of some very unique methods to minimize capacitance, current eddys, and provide the greatest possible conductivity. The center pins are hollow, made from Tellurium copper (OFC), they have a very high pressure, low resistance contact for ground. Best of all their cost is quite tame compared to other connectors that might be considered similar....I think you know what I mean. Considering this is a 31 year old company I might have had a top-notch RCA plug a long time ago. I wanted to keep this informative so you would know about these, it's clear few do.
