I agree with audiolabyrinth. A shorter measure of Ohno OCC wire likely achjeve the results you desire. or if you want a manufactured wired I get great results withs Jena Cables.
These days I sell Audioquest, Purist Audio and Kimber. The newer generation AQ is superior compared to the Kimber models. In timing, openness, drive and in blacks. Best blacks I ever heard from a cable. Wenn I owned the 800 Signature I played with the Nordost Valhalla. But the Redwood from Audioquest is superior.

I see you need long cables. With the TC8 and TC12 you will loose a lot of quality of what your speaker can give. The quality of cables are so good these days, that they are able to give you new talents which were not there before. What amp are you using? The most common misstake in audio is spending a lot of money at speakers and use a much cheaper amp and cables. Then you only play at a very low level of what your speaker is capable of giving in sound quality.
I did a lot of consulting. I visit a lot of people with expensive sets. But I never had a client with the need of 20m of cable. Wenn you spend this kind of money on speakers you need to spend a lot of money on amps and cables to get a good level in quality from your 800D. I had clients who got about 30% (quality) out of there expensive speakers. Because they did not have amps and cables which match the capability of there speakers. I could not blame them, because they did not know it.
