That would make sense in a way. Because a CD player has a much smaller

Not if they save someone $900. Where else should this be debated, the

I've never done it 16x, but if someone wants to come over and do it
16x, I'm more than happy to. I have done it 8x, with listeners

I'd really like to know who started this "rule of thumb", because it's
wrong.
If you can tell the difference between A and B 100% of the time, you'd
only need 5 trials
Don't get me wrong...I do like reading published measurements, in many
cases, they sure provide clarity that something scientific is behind
the differences I hear. Plus, I am curious, and I want to know why a
certain thing sounds different.
Better measurements don't necessarily equate to better

That's about the minimum that can give statistically signficant
results.

I could see a battery making a difference. Does this disprove the

I love this statement:
"the people selling these cables are hardly the
first people to notice that radio frequency
interference in the mains power might mess up the
sound of your hi-fi, so the power supply in your
equipment will be chock full of all kinds of
deliberate tricks to filter it out
Why not just use a large surge protector that offers seperate filtered
video and audio plugs. TrippLite makes some really good stuff. Throw in
some OFHC speaker wire and whatever interconnects you want to spend
money on and all should be well.

An EKG system (or oscilloscope, or what have you) deals with all the

However, this being an
There is a point to be made about how noisy the AC supply is, but a
power cord alone is not the answer. The answer, and one that more and
more audiophiles are recognizing, is getting off the mains completely.
In other words, going to battery power. I have a friend who is a
