Bi-Wiring

In the past, I have both bi-wired and used a single pair of wires (with jumpers) on the speaker end of things, no problem. I'm just confused about the additional binding posts on the power amp. Although @stereo5 suggests it's still bi-wiring, so the video holds true.

Biwiring helps if your speaker cables or connections are too small or poor.  

Use 10 awg cables and no need to biwire.

I don't like the double binding posts and jumper bars.  they are a huge mass that interrupts your signal.  I take both pair out and replace them with a single low mass binding post and hook both internal wires to it.

@carlsbad - interesting. I wonder how that would affect my warranty? Maybe in my case I could use 10awg jumper wires?

Well, it's not the first time we have been told it's more marketing than reality.  Paul at PS audio sheds a little light on why bi-wire may have been a thing at one time.  

@navyachts IDK. I never worry about warranty. I just worry about sound.

You probably have the big heavy cardas binding posts which are a huge mass that the charge has to fill as it passes through.  I think I'm in the minority thinking this is important and I don't think it is a huge effect.  I'm just into little tweeks that help. so unless you take out the big heavy binding posts, mods probably won't make much difference.

But warranty law is not well understood. For a manufacturer to deny a claim becasue you modified, then they need to show causal relationship between your mod and the failure. For example, if you put a high flow air filter on your car and the window fails, there is no relationship.
