I've had three separate engineers tell me otherwise. Nice try.

This went over your head, I see.

Where did I say the cables would be hardwired? INSIDE THE AMP.

Actually, I said the speakers, but it would be the amp that would not
receive UL approval.



It would be the amp that would not receive UL certification.

Understand now?

I don't know if there would be a UL rule against a mfr. hardwiring
speaker cables to the amplifier, or not. I have never had the urge to
do it, and can't imagine there would really be a benefit vs. a good
terminal connection, although the present day terminals COULD be
improved on. It is true that modifying an existing amplifier might
void its UL certification. Whether that would matter is a matter of
conjecture and any agreements, restrictions or ordinances the end user
might be party to.

IN US domestic use likely no one would give a ****.

Some building codes DO require UL approval or other specific
approvals for installed equipment, usually for commercial but that can
be residential too. Installed, means that: built in to a structure.

There are also other approvals some specific commercial equipment
needs. Altec PA amplifiers were specifically approved by fire boards
for use in emergency fire alarm systems, and I am sure someone makes
an equivalent now.

Companies whose policies require UL certification do so generally for
product liability reasons.
