And for the flipside of JohnK and F107s advice for bookshelf centres... I tried an M22 in place of my VP-150 and really didn't like it. It seemed narrow - was great so long as you sat in the sweet spot, but once you moved out of it, the benefit of a horizontal centre shone through.

Everyone's got their own preferences, but mine is for the Vocal Point series.
