From Jeff Rowland website:
"Various accessories such as power cords, interconnects, power conditioners, and even more so major components such as speakers, as well as analog or digital front ends, often have a significant effect on the sound of a music reproduction system.
Unfortunately, the sonic effect of such products is very much system dependent, and their particular desirability is very much a function of the musical and sonic preferences of an individual listener.
Therefore, as company policy, JRDG refrains from recommending any third party components or accessory products over other ones."
It would not make sense to provide any other than good quality generic power cable IMHO.
