I love powercords and have tried many cords over the last four years: Electraglide, Elrod, Shunyata mainly. Now I use all the above in my system. Ana. Vx on cdp, Epiphany on Pre and Elrods on amps and conditioner. What I have learned is adding cords are like adding spices to your food. They definitely improve your components/system! However, you must know where to put what so you would improve from your weakness. For example, if your system needs to be quieter, then use the Vx on your cdp but you need more dynamics then go w/ the Taipan. The more expensive models are like fine wine. They do get better but only if your system allows you to hear it. Occasionally you might get lucky and spend only $300 and get a huge improvement over $1000 powercords.
I suggest you try something that fits your system's budget and improve from there whenever your can.
