"...you'll find that one guy wants to sell you 10 feet of speaker cable for $100; another guy claims his are a LOT better, and they MUST be better because they cost $300 for 10 feet; and then a similar claim is made for a $480 cable. But if they all have the same R, L, and C—and each one spouts claims such as..."superior imaging"..."finer presence and less phase shift," etc., etc.—that strikes me as somewhere between fraud and hoax.
You can spend your money any way you want to. You can say that you hear a difference. But if I offer you an ABX test, you should not get mad at me and stalk out.
Some of my favorite "hoax" stories are just the claims that manufacturers of speaker cables tell about their wires. I really like the cable with "large-diameter wires to carry the low-frequency music, and small-diameter wires to carry the high-frequency music." (Of course, it's easy to compute that the skin effect of copper wire will make a 3° difference in the phase shift of the thin/fat wires at about 300 kHz. And, since the fat wires and the skinny wires are paralleled, you won't be able to see any significant difference in phase shift at 20 or 30 kHz.)
The other cable I'm impressed with is the stuff that has a conductive "insulation." When this cable's resistive losses match the capacitive and inductive attenuation and the conductive losses, and the phase shift is minimized, it should sound better.
Well, if it sounds better to you, go ahead and buy it. But, if it just sounds different, then maybe you do want to buy it—or maybe you don't. Maybe when you really turn up the volume, the conductive "insulator" will start to get hot??
Speaking of cables, my friend Tom said that his wife recently went to buy some new speakers at Circuit City. The salesman sold her some new speaker wires "because the old ones were probably worn out."
Additional amazing audio quasihoaxes:
When you have line-level cables (with RCA-type phono jacks), the expensive cables sound much better than inexpensive ones.
After you decide to specify the expensive cables, the ones with gold plated jacks sound much better than the solder-plated ones.
These cables have a preferred direction, and sound better when you connect them up in the preferred direction, with the arrows pointing from the tuner toward the amplifier.
In addition, these cables sound better if they have been broken in, or aged, with a special ac signal forced through the cable.
The best burn-in fixture for these audio cables uses digital signals to force current through the cables.
Needless to say, I've never heard of any one of these wonder cables being tested with an ABX box. Probably the "Golden Ear" person would object to the relays in the ABX box, as they would corrupt the signal. But maybe we could overcome those objections by using a digital burn-in circuit to burn in the ABX box..."
