I think (but I need to confirm) that the sound I heard from the Wilsons is the direction I want to go. Obviously this is going to require a minor adjustment to my 861 (another balanced card).

This will at some point need more juice to amplify at least L/R channels, perhaps leaving the others to the Showcase. This job will be filled by a much bigger Krell (or Krells). All this needs saving up for, but at least I think I have decided!

My only concern is all the extra cabling I'll have to accumulate to and the extra room I'll need to make for the extra amplkification that was going to be hidden in the speakers!
