(NEUTRAL) higher end quality speaker cable recommendation

[sdn660]

You could try Nordost (Norse series). Especially the first Norse series. Norse 2 sounds a bit warmer. I went from Ansuz (P) to Nordost Tyr. That was a big step forward. Nordost Tyr speaker cables are very transparent and open and certainly not warm. So they might give you the bite you miss with Atlas mavros. In my system Tyr matches well with my Sabrina speakers.
Hope this helps.
