Blazter, Seems like you'll be having a fantastic time!! Looks like you have a plethora of outstanding power cords to try with the Stealth(s).
From the sheer number of PC's you have, it seems that the condition of your AC is important to you. I would presume you've taken the steps to add a couple dedicated lines for your system.
I have seen a wave of people who have foregone the idea of power conditioners, filters, etc. in favor of mulitiple dedicated AC lines (one for each component) and good PCs specifically selected for each component.
Using conditioners & filters seems to blanket the entire system with a single coloration - which in my system, disrupted the uniqueness of my individual components and caused a breakdown in synergy coupled with a lack of transparency.
Be sure to listen objectively. The conditioners are initially very impressive... but if you listen close enough with the Stealth/Hydra/CFX, etc. in your system. You will hear a coloration. Of course it makes things different but... is it truly better? For some systems it may be good. But if your system is tonally balanced and without sharp edges, a line conditioner is not necessary.
In every instance with various PCs and conditioners, I preferred the conditioner on my DIGITAL only - which seems to defeat the purpose of having a multi-outlet unit.
For a really good AC "upgrade" which will not add color to your system - you might want to look at Dave Magnan's website for system tweeks
he has described and advised on how to build some very interesting DIY AC filters which could be the cats meow.
