I can't find a decent-quality audio extension cable anywhere. So I figure it would be better to use my existing male RCA to male 3.5mm Monster cable, and put a female RCA to female 3.5mm adapter on it. They don't seem to be in existence, only female RCA to male mini stereo. Could I perhaps purchase an RCA coupler and then plug my monster cables in one end and a male RCA to female mini stereo adapter (which does exist) to the other end? Thanks.
