I like and prefer the sound KLE Harmony RCA plugs, by Keith Louis Eichmann/KLEI, to the Bullet RCA plugs.
For me the Harmony RCA plugs are more organic and natural sounding. Also the range of the Harmony plugs is excellent for trying with the vast array of very different wire and cable configurations that are out there. There is an amazing number of wire and cable configurations out there that is for sure.
Going by the above posts, I guess that means I will also like and prefer the KLE Harmony RCA plugs more than the NextGen RCA plugs.
I guess that simple little dab of solder on the tip will also work for the KLE Harmony RCA plugs. Little tips like this one are always handy, aren’t they.
