Speaking of P.T. Barnum, here are his offspring:

I'll bet that the people who buy this crap would be aghast to know that the
power company has supplied their AC power through oxidized aluminum wire and
some of those electrons came from nuclear power plants and are radioactive!!!.

And there are those who spend hundreds of dollars on a-c power cords for
their audio systems that have been cryogenically treated to "align the

The problem is that human perception determines satisfaction, and perception
is not always based on objective data.

Subject: Re: [Elecraft] [K3] Audio circuit distortion
I once wired a guy's $20K audio system with RG8. He claimed it made all the
difference. He also claimed that vinyl was vastly superior to CD's. I told
him he had a wonderful imagination. The very best and cleanest vinyl with a
radial tracking arm turntable and a top of the line cartridge could just
barely make a 40db s/n. Digital audio can do 100db anytime. Many years of
selling audio gear taught me about the psychology of hearing. It takes an
experienced ear to appreciate a truly flat response. Most people prefer a
very unbalanced equalization.
I got lots of chuckles switching between a $300 system and a $3000 system
and having most people prefer the cheap setup.
Having designed loud speakers professionally (of which 1,000s were sold), I
am equipped with very refined and experienced hearing. Unless you were
listening to FM broadcast, how could you possibly appreciate a .3% THD? I
always assumed anything less than 1% was more than adequate for our kind of
communications. If we get down to this level of performance, we'll need to
work on the 50% or so of stations that only concern themselves with output
power - not audio quality. There is a lot of dreadfully distorted signals
on 20 meter SSB. Nothing beats working a station that is s9+20 and barely
understandable because he has compression and mic gain pushed up so he sees
1500 watts on his output meter all the time.
So, IMHO, the K3 has absolutely splendid audio when I have a chance to work
another station whose audio is actually adjusted correctly. It amazes me
that most rigs today have a monitor function. Must be the most unused
feature of all time.
