Which cable has most impact - IC, Spkr., power?

My last thought on this because it probably is one of those questions where there really is no definitive "answer." Shadorne's post makes a lot of sense to me and I have long been aware of all the pitfalls he cites and how they can impact on a cable's performance and "sound." However, in a system that doesn't suffer from any of the deficiencies he lists (I don't think mine does) it still seems to me that there should be a rule of thumb on which cable is most impactful in terms of asserting its "sound" in the overall context of a system. Oh well, another forever open question...

Ok, everyone is right.....
Remember..Your system is only as good as your weakest link !!!!
They are all important, ic's, power, & speaker c's. Don't
let anyone tell you your cables don't make a difference because they do.
Yes, many different flavors & prices. Find the ones that work well to your tastes & your system. If you feel ic's to start, go from there. I feel the synergy is important.

I think, the Amp-Speaker wire has to do a job for 2 tasks:
To deliver current and to handle the feedback from the chassis.
All other cables do the transport in 1 direction only.
Probably one reason why most experiiences agree with Speaker cable.

I would say speaker wire, I consider it almost a component in itself. Enormously important link in my opinion.

Shandorne's post makes a lot of sense but I have to agree with Joe also. Even assuming that one has the finest AC power and the perfectly constructed component, one would sense that one cable has a greater influence on sound than another cable. I am not an engineer, but are we saying that when one adds speaker cables, power cables or IC's to perfectly clean AC power and a perfectly built component, that their is no noticeable sonic change? If this is the case, than I have to believe that no component has ever or will be properly designed and perfect AC power does not exist. Since we haven't reached that point of perfection, It doesn't leave much choice but to pursue the pefection in another way. I suspect we are all going to be fussing with our cables and equipment for many moons to come.
