Smooth sounding Inter connects RCA RCA ? Any ...

Hello People,

Looking for smooth sounding IC for my system!
Ultra smooth to tame the system down a little without loosing resolution, well dont like my mids up my face kind a cable!

Cables I have liked very much hmmm actually my system first:
Meridian Source/Pre > Classe Power > Sonus Fabers

Cables I have liked:

Audience Au24 , even the Conductor was ok!
Cardas Golder Reference > What about Resolution Reference?
Siltech FTM series - Used for around $400 or so maybe if I am lucky

Any other suggestions - I do like some of the Audioquest stuff- The early stuff like the Opal / Dragon / Diamond

Not sure about the new stuff like the Sky/ Jaguar and the other - Are they more laid back or smooth in some way?

Thanks
