So I decided to do a real test:
Two ARC-5 receivers, side-by-side on the same antenna,
receiving the same WWV 5 MC signal
the first with a completely "stock" audio output
and the second with one of the more common
"CQ-VooDoo" extra-tube hacks.
(note: both files are 0.5 megs)
The first clip is the "stock" receiver, outputting its
clear, crisp and ample audio:

The second is from the ARC-5 receiver
that has had the "CQ-VooDoo" audio hack done.
If you listen closely, the distortion and
chaotic noises on the WWV signal created
by this "VooDoo" hack are obvious:

You can't beat a scientific experiment for proving a point!
