Newer audiophile trying to learn and build as money allows.

My question has to do with the Felix.
I was wanting to DIY some power cables for my VTL monoblocks. Could I build the Felix right into the cables? Maybe put it into a small box or PVC pipe. The power cord would then look like a snake swallowed an elephant, but is it a reasonable idea? Interested to hear your thoughts.
Would someone explain exactly what is happening throughout the Felix circuit, and why it would help?
