I have a good feeling about it so I'm loaning C&C BH to test the theory. I believe the soundstage with C3/BH and Havi will be rather generous, also Topping NX1 amp which people said works well. Plus, those who enjoy C&C BH's - LF switch can probably benefit giving Havi's low end a little nudge for certain genres and a little clarity boost.
For me laying down late at night the 3D stage and imaging is a lot of fun, the music is really 'alive', I was listening to Kryptic Minds last night there were samples floating around all sorts of places micro details popping up.It must have something to do with the driver placement and shell design because the imaging and soundstage have no right to sound like this for this price.
If you have a spare $50-$60 go for it Wayne, they will be keepers for sure. To keep things in perspective though if I listen to Altone it has more detail and clarity but they cannot match this imaging and 3D stage of Havi. I would take these over RE-400 in a heart beat.
