There are still a whole bunch of nut job audiophiles on the net. These guys are subjectivists. There is still an honest following of vinyl recordings, though. Some of the old records were very well done.

Engineer audiophiles have been building randomly switching comparison systems, to make an A - B comparison without any possibility of human intervention. Levels are made equal to 0.1 dB. Switches have pure silver contacts the size of dimes. The subjectivists are invited to bring in their system, and the engineering type puts in a very normal, very high quality, system of his own, and the comparison system swaps individual components from both systems one at a time using a random number generator.

Both guys sit and listen. You know what happens? Mr. Golden Ear, the Maestro, Mr. Subjectivist can't hear the switching when it occurs. Instead of realizing that he is a conceited fool, Mr. Subjectivist says that there must be distortion coming from the relay's silver contacts and switching transient suppressing capacitors, otherwise he would easily be able to tell his stuff from the more vulgar apparatus. (Some custom made D/A, A/D stuff being used for this, too. Turns out these guys can't hear a 24 bit 96 kHz D/A any better than anyone else.) Those dudes are getting a pounding.

You know about the $500 per foot speaker hook up wire? Can you believe these guys are buying special $500 cables to replace the 120vac to the power supply wires? Those dudes must vote Democrat. Sucker born every minute.

Wow, $500/ft, I didn't realize ~~sucker~~ speaker cable had gotten that high. After I had gotten to the point in school where amplifier stages, gain and bandwidth was old het, I saw a frequency response chart for some of that killer speaker wire. Yep, the response is decidely and measureably different. To a very sensitive machine. Certainly not in the range of normal human hearing.

In a previous life I designed about 200 separate movie theaters around North America. We used a belden factory twisted set of cables with 2#12 stranded conductors to each speaker. They're onl that big due to distance and the 3,000 to 6,000 watts available at each auditorium amp rack.

I have about 50 feet of the stuff here, just in case I ever wanted to due some sort of permanent install.
