I have no experience with the Leben, but have a lot of experience with integrateds in general. Thinking about it, I agree with Jaybo. You can establish a baseline for the performance of the Leben by starting with the stock cord. Let it break in/settle in. Then compare the Leben's performance with after market cords to the initial performance with the stock cord. This will help you in gaining perspective on the Leben's potential. There are many cords to consider in what a fellow Audiogoner calls "the power cord jungle." You will need to go through trial and error. But always refer back to the baseline performance of the stock cord with the Leben. I went through power cord trials this year with 9 or 10 different cords on my integrated and line conditioner. This is my advice. I cannot tell you anything except, you'll know when you hear the power cord you like.
