Power cord for CJ MF2500A

I have a Conrad Johnson MF2500A amp and it sounds really good. My only problem is the power cord is about six feet and it won't reach my wall outlet so I have to plug it into a power strip. Has anyone ever had an IEC bracket installed to allow for an after market power cord? If so, was there any improvement in sound? I'm more concerned with the ability to plug directly into the wall outlet than I am about using a different power cord. The supplied power cord works quite well and I have read that Conrad Johnson spent time developing the right cord to go with this amp.
