need your help again.............

i now know there is something to upgrading interconnects and speaker wire. my dilema is for the pre to pwr amp connect which is better. i am thinking of kimber kable hero, and audioquest king cobra or diamond back. they both seem to have good reviews. any one that has had dealings with these two are others in this price point let me know. i also like cardas cables as well. i have a conrad johnson 2300a and 2500a power amp and pv10a and pv12 preamp.
