i'll hazard a guess: is it possible that in the event of failure elsewhere in the component, you may have lethal charge present at the binding posts? this may be some sort of blanket "double insulated" norm to eliminate that possibility in products.

it must be very difficult to write norms for millions of variables, yet keep the documentation of manageable size for manufacturers and inspectors to read. attempts to simplify will result in redundant situations where the norms appears silly.

BUT the Cat5 cables honestly make a significant improvement over the stranded cables. It's such an easy thing to try and not expensive. You have three of us urging you to try them now so may be there is a good reason!
Sorry, I really could not recognise a significant change, with Cat5 cables (and my tube amps). BTW: my cables are 5 feet long.

Maybe, later I will try it again, this time with a gainclone.

But soon, I will play with the Cornu spiral horns (they still wait at the customs office, as they want to much custom fee ). Cornu gives me the chance, to search/develop a little enhancement for this speaker.

I expect more difference, than changing the cables. BTW: my experience tells me, that most time when such a detail changes the sound significantly, something in the chain is COMPLETELY WRONG!

Imho, you better search in this direction (eg. solve the REAL problem)

I am sorry!
Franz

P.S.
Before delivering the sold amp, I will shrink some plastic around the binding posts
... and write in the manual, it is forbidden to remove this isolation

Yes, that was the cause.
A norm made by idiots, for idiots.

Of course, security norms have to be idiot proof!

I do understand the banana problem

Default Idiots

I strictly disagree, norms are not made by idiots !!! Only this paragraph is not quite consistent - binding posts at amp must be insulated, but binding posts at box not .

Norms are not made by idiots, I agree.

But what do you say about this practice:

Click the image to open in full size.

Thats the way, the industry sells amps with this kind of postings.

And, you may excuse me, I will do the same! I got for free two plastic bags full of this pieces today from my local highend dealer, as he removes them from new amps.

Franz

BTW
The distance between my postings is of course not 19.5 mm!

The idiots didn't get a chance to ban banana plugs in this part of the world, because our mains plugs take flat blades, not round pins .

I could go on (and on) about the subtle but relentless "dumbing-down" of society by the "bleeding hearts", but this is not the place...

Guys, most brands use cheap plastic red-and-black binding posts.
I have a magazine here with a big Conrad-Johnson amp with beautiful nude binding posts.

And why do binding posts have to be isolated on the amp and not on the speakers?
Too many speakers use non-isolated binding posts.
I say to the burocrats: idiots.

Same here. I have seen people wire speakers with mains plugs, which causes a lovely fireworks & smoke show when it is plugged into the wall.
