Best IC and SC used under 1000 dollars for my system?

"Best...."

Yeah, good luck on that one. Suggestions will be all over the place.
Did your power cord give what you were hoping to hear?

Once again, subjective, and only your ears know what's best. Certainly, no one here.

 I use all Nordost from the wall. You can be assured, someone will post they find it does "this or that" so use brand "X" Nordost seems to be a polarizing brand.

I hear it as what it's intended to do. Pricey, but you can find used for half the MSRP or better. I wouldn't touch the stuff for retail, otherwise.

I would really love to get many suggestion. Especially with a link to buy. I forgot to mention it must be copper as Cube Audio suggested.
Triode Wire Labs would be perfect, I would like to bi-wire if there is an option, but it`s above my budget.
