There's no recent insight there. Maybe you should learn something
about gain staging before pretending that you can educate people in
this newsgroup on the subject. Not that you will ever understand it;
you seem to have given up on that long ago. Maybe you should find a
good advanced math forum, and explain to the readers there that you
have "new insight" into why 2+2 might be something exciting and stupid
in "vintage" math.

When you've come here with a question, you've thrown tantrums because
you couldn't understand the simple answers. And now you presume to
present information you don't understand. The next time you feel like
taking a dump, please don't do it in a newsgroup that I read.

Exactly what I thought. I made some attenuators 30 years ago to solve the
problem, which was really just a matching problem with other sources when
adding a CD player to an amp that was never designed for a 2V level. Any
good amp in the last 20 years or more should not have that problem however.
And one that does could hardly be called good IMO.

It's new insight the first time you find out that you can stop
overloading by using a pad. We all knew this stuff years or decades ago.
Others don't, so it *looks* like something fantastic and new.

Yes, but when normal people learn something old for the first time, they
don't usually race onto the internet to claim it as a "recent insight", even
if it is for *them*!

I have just had a recent insight that it is not a great idea to plug an
XLR speaker output (doncha hate those ?) into a mic input.

This info is so hot off the press I feel the need to show everybody how
magnanimous I am by sharing this remarkable revelation.

I had a neighbor who was a real tightwad. He had a pair of Acoustic
Research AR4 speakers (not sure which sub-version). He needed longer
speaker cables, so he used a couple of spare extension cords, the
zip-cord type. The cable coming from each speaker ended in a male
AC-power plug, which would be plugged into the female end of another
extension cord going back to the outputs of the amp.

Everything was fine until his mother-in-law decided to vacuum the living
room. When she finished, she plugged the speakers into the 120VAC
outlet. At 8 ohms, that is about 1800 watts at 60 Hz. Wish I could have
been there to see it.

This is why loudspeaker xlrs are wired HOT on pin 1 and COLD on pin 3,
that at least was what we did back in the old days.

A yes, the new kids on the block don't know that there is a different
standard for using xlr's for loudspeakers.

Hearing and eye protection is suggested.

Nah, they'd blow up long before it got spectacular.

A fire extinguisher would also be handy. :-)

The real standard is don't use XLR's for speakers, only for the amp output
of self powered ones. Usually just used to couple to another amp input.
