I am interested.  I've had very bad luck with all 6 power conditioners I've used in my system--all robbed the system of life and dynamics except the Audio Magic XXX Stealth which showed no improvement, but had no deleterious effects either.  My system already sounds great.  I have a whole batch of black boxes from Krissy with each one making a significant difference in sound no matter how many are employed.  IF the SR Powercell made even more difference than the black boxes did each, that would be nice.  If it was a substantial difference for the better in the ways you've mentioned, it would be well worth it.
