How to improve on Audioquest SKY

Have introduced the "SKY" into system( CD to Pre where it works best)--all components are Conrad Johnson with exception of speakers which are Vandersteen Quatros. Still working on getting my turntable into system. QUESTION. RE--INTERCONNECTS--Running Comets on speakers--interconnects for pre and amp are Audioquest Niagras--SKY seem to be a bit "brittle"--even after a good warm up---Niagras, on the other hand I have found to be a bit "dulled" out; nice but lacking in clarity--hoping to get some thoughts re alternatives---something warm but CLEAR in this system--DP2 is the CD--CT 5 is Pre. All thoughts and suggestions are welcome, but particularly from Vandy and CJ owners. Thanks. (Power cords are all Purist with exception of Audience Au24 for CD--- CD may need upgrade based upon the above--again--suggestions for auditioning?
