Its my understanding that CJ does not install IECs on their older equipment because they feel that an aftermarket cord would not be an improvement. At least that was my understanding when I spoke to Ed in tech service and Lew Johnson one day last year when I was at the factory. FWIW, I have a 2250A (with an IEC). Ive tried several aftermarket cords (including DCCA) and the stock cord, the one that CJ calls their hospital cord sounds as good as the aftermarket cords Ive tried. I've also tried the hospital cord with my Premier 16 II, and again thought that it was as good (or better) than several aftermarket cords that I've tried. Dont get me wrong, Im a believer in aftermarket PCs. They DO make a significant difference for the better on some equipment. For what ever reason, on the CJ equipment that Ive tried them with, to my ears, they do not. YMMV.
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.
