and the science is not exactly "settled." Yes, on the matter of audio signal traveling through a conductor, it pretty much is.
Scientists continue to study electricity and conductivity in great depth, today in 2010/2011. If we had all the information we needed to definitively conclude that conductors do not affect audio signals, then scientists would not still be avidly studying these things. Care to cite any relevant papers?
This is a very controversial subject, which to be fair you did not really broach, flargosa.
You've asked a perfectly reasonable question - "recommend me a cable" - which limpidglitch's deceptively wan remark has turned into a science vs. magic debate. No, he did it all by himself. And I'm so glad you chose to use that term, 'magic' 
These kinds of debates are not limited to the audio world, and by their very nature, will probably never be settled.
The very thing that the scientists think makes them objective (a reliance on quantitative data) actually makes their perceptions hopelessly skewed - it's over before it starts, for them. Care to elaborate on this? How does a reliance upon objective data make one biased?
And for those who think cables matter, the other side will always place a burden of proof on them that nobody can provide, regardless of whether they're actually right or not. The burden is not laid on the believers without reason. We can again and again demonstrate that one certain conductor under certain circumstances do not make an audible differences from a certain other conductor under the same controlled circumstances, but we can not generalize this and make it relevant to all conductors under all circumstances. You, on the other side, can with documenting just once that an audible difference exists disprove our stance claiming the opposite. Do you see the problem?
The debate isn't really fair to either side but it rages on, and on. And as long as there are money to be be made, it will continue to do so.
But for now, I think the only useful way to look at it is as preference. If you hear a difference, great, do your thing. If you don't, then just use your lamp cord and leave the others alone.
As far as your question ;) I would suggest perusing partsconnexion.com or takefiveaudio.com and getting some wire (I like the Jupiter silver wire) and sleeving to make your own cable. At that length, you can make something nice for easily less than $50. While I'm sure that silver sounds different from copper, I do NOT believe that a $300 cable is likely to be any better than a $50 one, providing they're both silver. You can probably max out the potential of an analog cable at $20 per foot or so, if that. The Belden I linked to is $0.65 a foot, is nice and flexible, have excellent EMI rejection characteristics and very low capacitance. Now beat that
