Considering the speakers that you mention in your other thread (assuming that you have electronics to match) I would save the $12 and put it towards some better cable. I am using a pair of the RS Gold on our mini system, right now, which is being piped through an SET amp and they do not sound very good. They sound best the first 20 or so hours of run in (during this time they are very smooth with very little detail, but they have kind of an ancient tube amp sound to them). After break in they are a bit grainy with recessed mids, somewhat harsh highs and so so bass. If you are on a tight budget you can find excellent IC's in the $50-$75 price range both new and used. Two new IC's that I would recommend are the Mapleshade Clearview Ultrathin IC's ($65 and it is a copper micro wire design) or the Homegrown Audio Super Silver IC's (approx. $70 or much less if you assemble them yourself from kit form and they are made of solid core silver wire, similar to Kimber KCAG). There are many other good IC's (or so I hear) in this price range as well.
