Hi, I have the same Exactpower setup. If you have "Magnan money" ;-) but would like real audio value for that money, (I've tried the Magnan) get a Purist Audio Design Dominus PC (with the Ferox shielding) for the EP. (None on Agon right now but should be $800 - $1100 depending on 1.5 or 2 meter length.)
For the SP, the best strategy is to power it from the EP as you said, but simply using a decent (but not necessarily g-e-n-u-i-n-e, expensive,audiophile cord ;-) My EP is in front between my (powered) speakers amp and sub. I have a very nice 16 foot long 12AWG 3 conductor umbilical cord going from the EP to the SP (which is on the sidewall with my source gear) which is to the left of my listing location. My system is as 'quiet as a chair'!
You should, however, consider another Dominus PC for your amp (if you want the most bang for your powercord buck ;-)
