I don't believe cables make a difference, any input?

If I may ask, how did that test look like?

No thank you Andrew. I do what I do for commercial purposes. I have 1000's of power amps out there, and sometimes one gets into trouble. I hope the the person with a problem duly reports the problem to Parasound, so that we can know about it and address it.

Unfortunately, I can't.

You can't what?

Have the two lectures been taken off the web?
I got through one and a half.
But Today I cannot get either back up.

I can't duplicate the test comparing coils vs no coils The tester has been dead for about 10 years, and I never wrote down the test procedure.

Looks like the AES uses some weird "security system" to protect views from non-members. The lecture is still availble to members but the URL changed. Why not become a member? It's not expensive and you'll get access to tons of valuable info.

Was that a sighted test?

[john curl]

Marcus, of course, it was an A-B test. Please just use coils and don't badger me.

I don't want to badger you, just trying to avoid prejudice But kicking out the coils without telling people for which application the Parasound amp was designed for was probably a bad design decision.
