you've been heard ;-)
the point you might be missing is that the evolution range is a line
interactive one, but more for small servers.
and these are generally in some server rooms.
for something more SOHO focused (and so less noisy), you should have
opted out for Ellipse MAX (still line interactive, with 2 outlets
groups too)

can I possibly contact you next week, when I'm back to MGE, to get
some more feedback?

now about the Powershare, these are things that I should have done for years...
but since I've taken over the project leadership, there are far too
many things I've not been able to give time to.
now, the situation has evolved since my Eaton'isation. I'll have more
and more time, and possibly somebody to work with me (but the crisis
might void this point in the short run though).
