I'm about to purchase a new system to replace my current setup. Getting a [brand and model] amp, [brand and model] DAC, [brand and model] speakers and (separately) [brand and model] disc player. Gonna cost me about $6000 plus whatever I end up paying for the disc player. The guy who's selling me the system wants to sell me expensive cables: $170 for a 1-meter RCA interconnect for amp and DAC, $250 for 20 feet of speaker wire. This sounds like more money than I need to spend.
As I said, I need a couple dual RCA interconnects to hook up the amp, DAC and disc player, plus speaker wire (runs of less than 10 feet per speaker) as well as a couple HDMI cables to hook up my desktop PC and OPPO to the TV. The rest of the cables I will buy are mostly USB 2.0 for my new computer and external devices and I suppose those are not so critical (although my DAC connects to PC via USB).
