It's just a standard IEC "computer" power cord. You can pick one up at Radio Shack or Best Buy. Just buy a 2 or 3-conductor/prong computer cable, preferably of 16AWG thickness or better (Denon uses 16AWG, 14AWG would be even better). The Denon only uses 2 conductors (no ground), but that won't matter. I'm using an upgraded 14AWG 3-conductor cable with my Denon myself.
Here's one that's available at most Radio Shack stores:http://www.radioshack.com/product/in...ductId=3875423
