Speaker cable recommendations please

Starting to think about what will replace my AQ Rockefellers. I feel like these are now possibly my weakest link.

Amplifier is the Ayre AX-7e, speakers are Amphion Argon.

I guess I like what many others do: excellent detail retrieval, tight punchy bass, realistic mids on the warm-ish side, non-fatiguing highs. Overall I prefer clarity/neutrality/detail over warmth.

Budget would be up to 1000, for used.

At some point I may give the anti-cables a trial run, just to gauge the hype. I don't see how these wouldn't be a downgrade though given the cost difference against what I have now. Who knows....?
