Oh, I'm sure some psychiatrists could have a field day trying to figure out 
what is going on with that crowd.  but, after a few weeks talking to them, 
they'd have the doc going to sound system auditions with them and discussing 
the finer points of running pure silver bus bars down the middle of your 
living room elevated 4" off the floor with crystal pyramids.

You need to have a little grounding in physics to realize it is all smoke 
and mirrors.

Only suitable for callow kids, this junk. Once you get to a certain age, 
your ears are fucked anyway so it doesn't matter how much you spend.

It doesn't require much grounding in physics to realize that as the 
juice just went through 238 miles of bird-shit encrusted aluminum cable 
to get from the plant to your home, the 6 feet of IEC cable probably 
isn't going to make a whole lot of difference.

Years ago some outfit was selling a heavy brick to be installed on top of your 
power amp.
Their claim was that it would improve the bass, reduce distortion and improve 
sound definition. I'm wondering if here are other venues where this level of 
foolishness prevails? Is anyone in the market for gold plated pure silver 8ga 
litz wire. ;-)

** It is easy to demonstrate the effect of a DC offset on the AC supply.

Just fit a suitable diode in line with something that is resistive and draws a few amps - like a heater or hot air gun. The load current of the heater will reduce the voltage peaks on one polarity by a volt or so - creating an average offset of about 0.5V.

Most toroidal supply transformers powered from the same AC outlet will now hum audibly. Some regular types will do the same, long as in each case they have ratings of 200VA or more and are unloaded or only lightly loaded. 

If you can monitor the AC current being drawn by the transformer on a scope - you will see the waveform is large and very asymmetrical. 

In a bad case, the additional current in the primary approaches the maximum rated primary current for the transformer. 

This article give more detail and a simple fix for the problem.

I know my good AT sounded quite a bit different on different stereos, and turntables. It went up to 30 KHz so I would assume it would need lower capacitance cables. 

The issue of interfacing the pick-up to the turntable and to the
amplifier has been known for decades.

The QUAD QC 22 preamplifier introduced in 1959 had a tube socket like
connector in the back, intended for plugging in a passive phono
module, consisting of resistors and capacitors, it was intended for
trimming the load capacitance as well as fine tuning the RIAA
equalizer. There were different modules for different cartridges, so
if you had to swap the cartridge, you could also swap the equalizer
module on QUAD 22..


BTW, ask any audiophool if they have ever been in a symphony orchestra
concert and where they were seated :-)

Have a brandy during the intermission and the rest of the performance
sounds even better :-) . You can also buy a lot concert tickets and
brandy for the price of audiophool products.

I think taking advantage of the mentally ill would be a violation of 
ethical business practices.

Even the rich mentally ill.

You might gain $6800 selling a botique IEC cable, but you will have 
certainly sold your soul. ;-)
