Cardas cables

I'm currently using Cardas cables throughtout my setup with Golden Ref's interconects, speakers cables as well Golden power cords. Whilst I love the trademark warm, rich qualities (saw someone even call it sweet) and deep soundstage of the cables I might be over doing it a little and would appreciate suggestions whereby I could perhaps introduce some detail or airiness without compromising the Cardas sound.

I'm thinking the best place to start would the Power cords. Suggestions.

PS:Setup consists of Rowland (Concentra II) Amps and ProAc (Response D15) speakers
