i need 20 meter speaker wire, decent quality

You might check with your installer to see if it would be easier for them to run 2 separate runs of the solid core cable through the walls at a time if you were thinking of having the cables bi-wired on the amp end. The solid core wires are fairly stiff, and trying to push or pull all four cables from a bi-wired pair through the wall at the same time may be a bit tricky for them. They will go through easier in most situations one pair at a time. You would then just attach both spade ends (2) to each output binding post of your amps for the two pairs, instead of crimping/soldering the wires into a single spade at the amp end. This "double run" would be the same sonically, but possibly easier to handle around tight bends in the walls if that might be the case.
I just noticed that you showed two different stereo amps. Are you bi-amping the speakers with the two amps, or just using one of the amps and bi-wiring it to the speakers?

Some of you guys have been suggesting ways to raise the speaker cable off the carpet, which I am currently doing with some clear plastic stands I got on this site. My questions is this: will it actually make that much difference when the cables are going to be real close and actually touching the inside of the walls they are running up and down through? Only aobut 6 ffet is going to be exposed. The rest will be within the ealls and attic.

Just curious. Are you running the Krell and Pass amps at the same time, or just deciding which to keep?

You will probably need just one per speaker if they only go across 6 feet of carpet once coming out of the wall.

I though i already answered this but maybe nont?

It seems i always have extra amps laying around and I am not sure which amps i will have running this system. when the speaker cables get here I will try them both and go with the one that sound the best in my system. I am using a Krell TAS to run the center and two reats.

I currently am using three speaker wires holders per side to keep the cable off the carpet. My question above posed the question how much good will they really do when you have 60 feet of the same speaker wire running up and down the insides of the walls where it is obviously touching the wall itself?

I think sometimes these little gimmicks are kind of blown out of porportion.
