I've had my pair of V7s in old Symphones aluminium sleeves running in a for a few hours now. The aluminium tends to make them a bit brighter than wood, so the result is somewhat v-shaped in sound. I'm not sure if the bass will drop down any more as it has with previous versions of the drivers, but I'm good with it either way.
Where I really like them is out of the Chord Mojo. They don't scale up to the level of detail of my main system, but they are so pleasant to listen with that I don't care.
