Craig - My intention is to save you money. I am sticking to the most obvious hoaxes. Line cords, power distributors, outlets etc. aren't in the signal path and can't even theoretically have an effect. The psychological aspect is not something that just affects the weakminded. Everybody, myself included, almost always seems to hear a difference when something is changed. The more you expect to hear a difference the more likely it is that you will.
Take line conditioners. The idea that a line conditioner reduces noise is so outlandish it can't be ridiculed. The electrons in the wire have been around for 15 billion years. Shuffling them back and forth for a few hours in an attempt to change something is preposterous. Does this stop people from hearing a significant difference. NO.
How about those arrows on the phono cables? The manufactures know perfectly well that the exact amount of current had better flow in each direction in those wires. Does that stop them from putting arrows on them. NO. They must have a very low opinion of the intelligence of audiophiles. Do you think people would hear a difference if they installed the cables with the arrow point opposite to the manufacture's suggestion? Of course they would.
Buying expensive line cords is another act of insanity. Think about it. On one end of the cord is a hundred feet of ordinary wire going round and round the transformer core and on the other end of the cord is several hundred miles or ordinary wire going back to the power source. Even if there were something special besides the price of the cord, what good is 8 feet of cool wire in line with hundreds of miles of ordinary wire going to do?
I say don't waste money on outlets, power cords, line conditions and cable conditioners.
I think exotic speaker wire is bogus too, however, at least it is in the signal path. I am going to test some cheap wire, the kind I use, as soon as I get the test equipment I have on order. The test is simple and will measured effects down to a small fraction of a db.
Spend your money on good speakers. That is where the action is. Even the very best speakers have much higher distortion than a Radio Shack receiver - as long as you are not driving the RS to clipping.
