An analysis would be futile when you're dealing with people who believe they need power cables that are $400 a foot because they make the system sound better. I got a great story for that, too. A new audiofool neighbor moved in under the main lobe of my 1500W HF ham radio station. He installed his $20K stereo system with the train engine starting cables to the speakers, big enough to crank the train with no loss in voltage up to 800 yards. I could hear a terrible buzz right through the walls of my house from way over there when my packet radio modem keyed up the beast for a beacon. Man, those are SOME audio power amps! Are they 240VAC? 480? 3 phase? Well, my ham antennas are pretty easy to spot. Looks like a little VOA installation. I'm responsible for any toaster that won't toast within 20 miles. "It's that damned ham radio of his!", they curse. I guess he didn't notice them before he moved in. Of course, I got a threatening phone call, referred him to FCC so he could get the free RFI booklets, all very friendly and helpful. "Listen, I'd be happy to come over and solve YOUR interference problem. I'll even pay for the new cables and any connectors YOU need.", I offered. After he cooled down a few days and his BP dropped below 200/170, he asked what I wanted to do. I wanted to replace the starter cables with #14 foil-shielded mic cable, because I had a 500' roll in my service truck. Oh, ballistic we went again. That would make his stereo sound like a Radio Shack Flavoradio! Oh, God, NO! Ok, let's compromise. I'll come install the new cable and we'll compare it to the battery cables off the train. Should be easy to hear the difference, eh? Wrong......There wasn't any difference in the sound. There also wasn't any RF feedback from the speaker-leads-acting-like-big-antennas back into the input balancing act of the big DC-coupled power amps, either. 1500W on 20 meter SSB never made so much as a click. The cable is made for XLR mic cords I make up for churches whos PA systems I fix. The speaker was hooked to the two #14 conductors and the foil shield drain wire was connected to the stereo chassis ground lug and left open on the speaker end, creating a Faraday Shield (the late Michael Faraday (1791-1867): http://scienceworld.wolfram.com/biography/Faraday.html would have been proud of me using his invention. Happy neighbor, now good friend. Several audio myths blown all to hell. Better informed consumer...(c; If you want real proof, look at the back advertising section of Stereophile magazine and see what's being sold, how much it costs and what it claims to do. I have an audiophile friend who falls for all of it. 20 watt mono tube power amps at $20,000 each. I'll bet his system cost him $100,000 or more and it only has an incredibly expensive turntable as a source. There isn't a CD within eyeshot. I'm an ASCAP and BMI-licensed DJ and do a lot of outdoor audio work for parties, car lots, etc. Thousands of hours of MP3 music on 360GB of hard drives pumping a nice DJ board from Winamp (before AOHell) with compander and cross-fader plugins. It runs itself until some cutie has a request to look up at the party. Time and Time again I have been asked what kind of source I use for all this wonderful music that sounds SO good being played through APPROPRIATE speakers, those that require TWO people to lift and load, not something 6" across in a pasteboard box labeled "woofer" by Tweeters at $800. The just can't believe it's ALL MP3 music being played. (No, I can't hear the 128Kbps sampling rate, either...(c IBOC will be perfect for those who are content with 64kbps MP3s and have no live music frame of reference. Look at what the manufacturers did to AM sections of their radios. I don't think that's where good quality is going to come from. I'm still wondering why we're buying IBOC, now that "music" is no longer played on AM, AT ALL, outside of Nashville's WSM. Who needs to hear Rush or Bill or Gripe Radio Locals in digital? A little white noise makes the program more interesting! The best test is with a very high quality pair of headsets where you'll hear every artifact up close. I can't even listen to C-Quam because of the gyrating stereo image. It causes motion sickness standing still. I'm very protective of my Sennheisers, here. Have you played with those $150 little plastic Bose phones? HOW CHEAP they're built! Best Buy can't keep them out for a demo because the plastic headbands keep snapping off. Most all headphones over $20 have about the same sound. BUT, I rate them with NO INPUT. I put them on and move around, listening for the headphone-induced, plastic creaking noises most all of them make. The better Sennheisers are like HEAVEN in comparison to most other brands......they just don't CLICK OR CREAK...which drives me crazy. I seldom listen to "broadcasting" any more because I used to be in the business back when you HAD to actually put program material on the air that didn't include an 800 number and playing 40 minutes of Di-Teck Dot CON per hour would result in license revocation and heavy fines.....you remember....when the FCC was run by SANE ENGINEERS, not political hacks and lawyers trying to sell off the publics property on Clear Channel's payroll.
