I will second Bigkidz recommendation of the JPS Power, but I actually haven't heard it! I did build a power cord using JPS in-wall cable, however, about 6 weeks ago, terminating it with Marinco 8215 male and 320 IEC. This cable will come in at around $100 for a 5 footer and is supposed to be VERY close in performance to the JPS power (according to the dealer I bought the raw wire from who has compared both, and also suggested that it would probably be very close from the dealer I purchased the Marincos from) at less than 25% of the new price of the JPS power and about 40% of what used Powers typically go for on Audiogon. All I can say is that for $100 it is a killer cord, with a real bottom to top coherence, smoothness and great bass performance as well. Not as warm, I think, as the Cardas Goldens I have in my system, this DIY JPS is probably more dead in the middle neutral. For $100, I would think it would stack up very well against cords going up into the $400-$500 range, and if you have the need, you can do multiple cords in your system for $300.
