I have posted this before, but here it is again. There is an Ebay seller, MATTJK, who sells DIY ICs, digitals, and PC at very reasonable prices as well as different price points. I have his $64 PC and $20 ICs and $10 digital. I also have NBS Mine/Serpent II IC/digital (for sale on AudioGon) and have compared these at length. If you are on a tight budget, I would recommend trying Matt's cables. Here is the URL to his current auction for his $20 cable:
