568.1 is more detailed and smoother than the 565 by some margin.

The 568.2 adds a little something to the smoothness and detail again. The 2.55b firmware adds a little air and detail but still sounds smooth.

The G61r and G68 family added detail and sounded more open but lacked some of the smoothness of the 568, although the apodising may have changed this I don't know?

The 861v4 I thought gave you the openess of the g serious but the mellowness of the 500 series.

I always thought that 568 could be improved slightly and the same for the G series, however, never really found anything to fault with the 861v4 (apart from the price when I was trying it, of and the size).
If I could have afforded to swap my G61r for the 861v4 at the time I would have done, it just seems to get everything right.
