I'd welcome that. I've got quite a few classical surround SACDs but with only a select few being other than the 'in the hall' approach. Most sound excellent but I'd be curious to learn of titles that bravely place discrete elements in the surrounds.
There's an old Naxos DVD-A of the Four Seasons with Concerto For Double Orchestra on the same disc that had one set of musicians across the front and another in the rears, I'm sure Brett knows the one?
