ETI Research Kryo Audio Connectors
ETI research makes some of the finest audio connectors available, period. Their attention to metallurgy, physics and construction over audio bling means you get solidly built, great sounding cable terminations that don't cost a fortune. Don't get me wrong, they still look great, but don't scream "look at me" the way some other premium audiophile connectors do. They put their development resources where they matter.
