I would buy all of the cables from Radio Shack. Even the one he would pay for. I would buy some spools of their magnet wire, and make my own cables to my specification, just like I have already done on my current system. If I had to buy the RCA plugs there too, I could live with that, although I'd like better plugs. I use bare wire connections on the speaker wires anyway.
Alot of you are probably thinking: There goes that crazy TWL again. Now he's advocating Radio Shack home-made cables for a high-end audio system. Yep. And they work. And they are not alot different than that Sakura OTA cable that got a couple hundred posts on the thread about it. Now, I am not saying that there aren't better cables out there, but I am saying that these are good cables, and they might even provide better synergy with certain systems than any other one that might be available. And if you tried them and didn't like them, it would hardly be a great financial loss, since the total cost of a set of ICs and speaker cables would only cost less than 1% of the cost of a set of Valhallas. That's less than the sales tax on a set of Valhallas.
