Just wanted to say I recently purchased Audioquest Yosemite RCA's. My system is budget high-end, imho. Bass is ever so slightly more forward but extremely clean, bass riffs previously unheard to this degree of accuracy. Midrange and treble are also equally pristine. Great timbral accuracy. Very good micro detailing and black background which makes imaging excel. Hearing midrange textures and nuances I'm unfamiliar with. Really good cables, imho. I have not compared to other expensive cables, only cheaper Audioquest stuff and no name cheapo stuff.
Someone previously mentioned that you can get FEP insulation for much cheaper from companies other than Audioquest. I've seen teflon dielectrics, but Teflon has come out to be a nasty product that breaks down and leeches into everything, so not safe, imho. I have yet to see another high end cable manufacturer claim FEP insulation. Can anyone direct me?
