I have the Impulse on my Cdp. After 200 hours of break-in, there was just as much improvement as on my tube preamp. It seems that the more Fusion cords in my system the better. The manufacturer, I believe, has a return policy if not satisfied. Talk to Kirk or Eric. It's difficult for me to describe the overall improvements in words. Just imagine all the superlatives and adjectives used to describe the musical qualities most audiophiles crave and these cords give them to you. I don't hear any drawbacks. The tonality of these cords is very neutral, so if you're looking for some cords to add additional warmth or added brightness, then look at other cords. To my ears, dollar for dollar, superior to Elrod, Electraglides, and many others that I've tried. But then again, your equipment, room, listening preferences might be different from mine, so your mileage might vary. Have fun experimenting.
