Clayeton, what power cord came with the 17LS? The reason I ask is that I tried several different PCs with my CT-6. The factory PC that came with the CT-6 had what CJ calls their hospital grade cord. At least I think that is what Lew Johnson told me they called it. It has a clear plug. When I switched to a Premier 16 the aftermarket cord I was using with the CT-6 automatically went into the 16. After seeing your original post a couple of weeks ago and remembering that several people on Agon have already commented that aftermarket cords did not make a difference on their CJ preamps, I plugged the CJ hospital grade cord back into my 16. Voila, the factory cord actually sounds much better, particularly in the mid to upper ranges. Moral of the story, dont discount the factory PC. If your 17LS did not come with the hospital grade cord, you may want to order one from CJ and try it on for size. I dont know the price of the cord, but it has to be cheaper than some of the crazy prices people (including me) are paying for aftermarket cords.
