Hi Lev335...
I had the same question a few months ago so I played with 5 different power cords on my Quest Zs. I started with Synergistic AC Master Couplers and finished with BMI Whales. The results with all of the cords was virtually the same no matter which ones I used. There was very little (if any) improvement over the stock cords. I also tried plugging the cords into a line conditioner to see if that would help. Still virtually no improvement. Curiosity got the best of me so I emailed Martin Logan. I was told that power cords did not affect the sound at all because the speakers just needed a light electrostatic charge to operate. No "mega-current" cord was needed. After my experimentation, I have to agree. Spend your money on power cords for your components. Hope this helps...
