A question for you audiophiles. I want to connect my sound card to my receiver so I can get my computer's audio through home theatre speakers. I also want to convert my remaining cassette tapes to digital. The RCA to 3.5 mm jack cables come in a huge variety of prices, from a couple bucks for el cheapos to a small fortune for Monster cables to somewhere in between for mid-priced ones. I'm wondering just how much difference there will be in sound quality, considering what I want to use them for. And how important is gold plating? Thanks.
