Don't tell them that the wiring in the wall is most likely romex that costs

A good power cord is like the onramp to a freeway. It gives the
electrons a chance to get out of stop-and-go traffic and flow smoothly
and quickly into the device being powered.
The pot-holes on the surface street (romex) aren't important once the
smooth flow of electrons is re-established.

The audio distortion of the K3...
One can laugh about this, but let us face it. There was a lot of
laughter about the reported audio artifacts coming from the first few
/thousand/ K3's. At first it was denied by many.
It took quite a while until people were convinced that it realy was a
How much of the audio quality described in the recent threads can be attributed
to the audio circuit distortion, as reported by Rob Sherwood at this year's
Dayton Contest Academy? The K3 audio section starts around 41:40 into the video.

I watched the presentation again. Yes, Rob said the K3 was fixed in 2008. He
also said the fix wasn't as good as he'd like. It didn't compete with the 0.3%
distortion of the Icom 756 Pro III. So if you look at the distortion products
at 44:20, would the average amateur (like me) be able to hear
Given that a decent stereo has a total harmonic distortion of something
less than .05 percent, you might be able to hear those distortion
products, but what would that mean? Most amateur communication is done
surrounded by noise or immersed in noise, with imperfect signals,

I had a guy working for me who was a musician and audiophile who claimed he
could tell the difference. I referred him to Bob Pease.

I haven't laughed so hard in a long time. How ignorant their customers must
be. I really enjoyed the 4 for $115 covers for your wall outlets that would
keep RFI out of the wiring. Wonder if they would cure RF feedback :-). So
much for the laws of physics.
I think the rain and fog has gone to their heads. LOL

Single numbers like this are quite inadequate to describe distortion.
There are MANY kinds, and many manifestations. THD is a particularly
poor metric for non-linearity, because some
