**Go and study up on Thevenin's Theorem and get back to me. However, that is 
not the issue. And you (should) know it. The poster who began this whole 
fiasco, which allowed you to demonstrate your incredible lack of knowledge 
said nothing about the sound coming from the speaker with the short on the 
speaker cable. I explained to you at the time (an explanation which you 
ridiculed, BTW) that it was highly liklely that the protection system was 
not activated until moderate levels (just as the poster suggested) because 
all the other channels were still operating. I patiently explained to you 
that this was, indeed, very possible, given the likely protection systems 
used in most commercial amplifiers. You denied that my explanation made any 
sense. Of course, your suggestion that I was incorrect held no weight with 
any reader on any forum, given your complete ignorance of modern electronic 
devices and their technical features. It is this point where I am most 
incensed. You STILL deny that I was correct, in spite of the fact that NOT 
ONE SINGLE poster has supported your nonsensical stance. Not Arny, not Dick 
Pierce, no one. You're out on a limb and completely out of your gourd.

**Really? Let's talk about obsolescence sometime. See how much a 5 year old 
receiver sells for. Then go price a 10 year old Krell. The Krell will have 
hled more of it's value than your 5 year old receiver.

and stay on topic and keep to the facts. I proved you wrong. You know (or

**The poster said that the amp did not shut down 'till moderate levels were

**What is a "standard speaker load"? How can you guarantee that an amp 
remains below clipping at ALL times?

**Wrong.

 Tell me, just how often do you recommend heavy

**Pretty much every day, in fact. It's all most people need for their crappy 
surround sound systems. Anything else is massive over-kill.

 Do you push the

**Nope. Never. In fact, I never "push" fancy speaker cables. Depending on 
the system, I may make a reccommendation for low inductance speaker cables. 
I even suggest where people can buy those cables. Dick Smith Electronics is 
one of the outlets I suggest. Which, of course, you'd know, if you did even 
a modicum of research. DSE sell the fancy, low inductance cable for 4 Bucks 
a Metre. Google it, if you don't beleive me.
