My suggestion would be to look into TG Audio cables. I was using Elrod power cords everywhere (Statement II on the amps, and EPS 2 Signature on the digital boxes and preamp. I switched from the Signatures to TG Audio SLVR and gained exactly the changes you're looking for - the sound is more neutral, more detailed and more nimble. In comparison the Elrods were a touch too warm and a bit thicker sounding in the low mids/upper bass. Replacing the Statements on the amps with Argent Audio Brujo HC had exactly the same effect.
TG's High Purity interconnects and speaker cable are among the very best, IMO. They give a very natural sound, with exceptional clarity and image structure.
