Anyone tried Voodoo or TG Audio PCs?

Everyone here seems to rave on the BMI Whale Elite powercords. But at $400+/cord, it is a bit hard to swallow for me to buy 5 cords. I've noticed two other PCs for around $200 -$250. One is the Voodoo Mana, and the other is the TG Audio HSR-i. Has anyone tried these cords? Is the Whale Elite that much better that it is worth $400?

My system consists of:
digital source: Mark Levinson #37 (transport) + Genesis Digital Lens + Sonic Frontier SFD2 MkII (D/A)
analog source: Michell Orbe SE + SME V + Benz cartridge
phone stage: ARC PH3 SE (detachable PC)
preamp: ARC LS-2B MkII (no detachable PC)
amp: Mark Levinson #333 (no detachable PC)
The digital fronts and the preamp are running through a PS Audio P300 with 2 Synergistic Master Coupler and 1 Marigo PCs. The P300 is plugged into the wall through a MIT Z-Cord I. I've just started setting up my analog rig, so I've been looking for a powercord for my phono stage, one to replace the Z-cord, and if I noticed that much of a difference, replace those on the digital front.

Any suggestion on how to proceed from here would be gratly appreciated too. Maybe a comgination of various PCs?
