UL approval applies to mains connections, not speaker connections.

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.

Well, I do admit to making that mistake. I thought I had said
hardwired into the amp, not the speaker. No wonder you were confused.
So I apologize for that. Scott, however, is not off the hook for his
out-of-line comments.

One hi-fi manufacturer, someone who had a Ph.D. in electrical
engineering, said that he had hardwired his amplification at home on
both ends (in the amp and in the speaker), and it was by far the best
method for terminating speaker cable. He said he wished he could do it
in his products, but he couldn't get a UL approval if he did. Another
engineer in the room nodded in agreement. So what this tells me is
that an UL approval is a highly desirable thing in the elctronics
market, and it makes the difference between doing something one way,
or doing it another.

Scott's strange, disconnected comments don't seem to address this at
all, but rather reveal another one of his mindless audio vendettas
against me. Too bad he's now 0 for 7. I wonder what it's like going
through life wrong about EVERYTHING.


*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.

Agreed.


*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.

That, and marketing as well.

By the way, I know someone who works for th Border Patrol in Southern
California. Her assignment is to find counterfeit merchandise (i.e.
batteries, electronics, etc.) in local stores. She always looks for
two things: the UL certification, and whether or not words are
misspelled on the packaging. She showed me a package of "Everedy" AA
batteries to illustrate her point. It was also missing the UL stamp.

So UL approval is much more important than Scott thinks, not that he
would notice if he was using Energiser batteries or not.
