IC's and Speaker cables

Question is -How do I "tame" an overly accurate response.

So you are looking for an inaccurate response? Not sure I understand this.
Before looking for cables to effect the desired change, have you ensured proper speaker placement? Is the room treated?
I'm not sayin don't upgrade your cables. But in my experience, cables make very subtle sonic differences if at all. If things aren't right to begin with then cable changes make even less difference. My experience, YMMV.

Speaker cables always appealed to me intuitively but in fact the biggest change occured with a change to a Cardas IC between my preamp and amps. Nothing however can compare to a component change.

For clarification, I worded that wrong. I want an accurate response but don't feel I'm getting a quality one with the existing cables. After some serious upgrades I still have my "old" cables. $40 IC's from Wireworld and $80 speaker cables from Transparent. I feel some of the missing warmth and accuracy is related to these units. I may be wrong, but am willing to upgrade them to find out. Thanks

I'm a fan of Gregg Straley's Reality cable line. You can outfit your system for less than 2K with money to spare and not feel that you missed out on anything. Very good stuff and friendly/knowledgeable owner.

Hickbone - Have you swapped with cables with something else just to see what changes? I'm thinking basis hardware store cables or something similar.

One of these days I'm going to purches a set of the Blue Jean Cable 10 awg speaker wires to compare to my DIY Cat5 based wires. The two designed are completely different so one would expect to hear some difference. I have my old monster cables sitting in front of the TV waiting for me to get motived to swap them back in for comparison.

Just because you think that something can be improved with your speaker wires, you can't assume that it means that more expensive cables are the answer. It's possible that something cheaper might sound better to your ears.
