Jaguar,
There is a difference, as I stated before, not a huge one as changing cords on components, but it's there. You have to listen for an extended period of time, not just swap cords and try to hear a change! Also no offense, but the QuestZ is an older speaker that does not have the resolution that the newer speakers have attained. There are a lot of variables to take into effect, the age of the house, the age of the wiring, the type of wiring, and time of day, and state of mind when listening! if you could not hear a difference between 5 different cords then I guess we are all wasting our money on PC's. In my original post, I should have stated the EEL's instead of the Whales. The Whales are being placed on preamp and amp, the EEL's on speakers! You are correct in stating change cords on the components first! Of course Martin Logan is going to say that, they have to keep the production costs down.
