I just picked up a VH Audio Flavor 4 Gold with the intent of trying it out on all my components to find the best match, including my RGPC 400s mkII. However, it sounds so good on my amp that I will probably just buy another one to try throughout the system. Its the most improvement I have ever heard with a power cord swap.
I have tried a PS Audio Prelude on the 400s with no noticeable improvements.
