IC's and Speaker cables

OK, I need IC's and speaker cables for my system. I have no idea where to start. This is the last of my quest. I have KEF 207/2's a Pass Labsx350.5 and Aesthetix Calypso pre, Music Hall 9.1 TT and Marantz SA004 CD. You would laugh at what I have for cabling now. Question is -How do I "tame" an overly accurate response. As my speakes are rated relatively "low"(25hz) I want some "weight" to my sound.Some "oomph". Budget is dependent, but up to $2000 for both IC's and speakers. Thanks

I have used Harmonic Technology Magic with the Pass and Aestetix gear with superb results. The Harmonic Tech Pro Silway III is REALLY good too and less $$$. Harmonic Technology Pro 9 speaker cable used is a bargain and again REALLY good.
I am seriously looking ay Harmonic Tech. Is it the Magic or Magic II IC? I have read nothing but good things about the Magic II but don't know much about the Magic. I have also been looking seriously at the Pro+(Bi-wire.)I would drop coin on either if someone strongly recommended it in a similar system. Thanks for the reply
ASI livelines (used). You'll have to jump the spkr cables.
These are such good cables.

Good luck.
