I seem to remember that one manufacturer - PS Audio, maybe? - has power cords that feature a removable ground pin (on the plug that connects to the wall socket). That way, you can use the cord with your 2-pin setup.
Yes, the two prong power cords are known as a C7 connection. Most of those supplied with audio components are chintzy and of poor quality. I have purchased two C7 power cords, one Audioquest NRG-1.5 (6ft) and one PSAudio. One was for my Marantz Blu-ray DVD player and the other for a Marantz multi-channel SACD player. Both are great and I can not tell the difference that much. The PSAudio is their entry level power cord.
