Avalon Eidolon matching speaker cables and IC

Thanks for answers, i accidentaly added two threads of same type, sorry.

I live in sweden, and not in any big city so borrow and testing in my home is very difficult. I have to go on what i read, by the most i do a lot of research before buying and most of times im happy.

Somewhere i read Avalon uses Cardas on demos, but i also read some pepole have the same opinion about Cardas not very good sounding cables.

Audioquest did i read some recommend to Avalon, and Nordost is fine cables. i would think Odin would be great but way out of budget for me. When i did have some transistor Class A monoblock the sound was very sweet, not to muddy but warm and sweet, but since i changed to Class D the sound have been thinner, more neutral, Nordost might be to much?! I uses mostly Copper cables but i think some silvercables could be a good match.

Thanks all for answer. As you say M-db the NC400 is probably a very good amp, especially at the cost of it. But i feel since i changed to the nCore´s the sound have lost some deep in music. I probably will change to another amp in future. Mabye an integrated Devialet 200, also Class D but i think a even better one. A long time "Dream" have been some nice Tube amp but some circumstances make them have to wait.

Regarding cables, i appreciate all opinions about cables in overall and matching with Avalon especially.
