What are the difference between the Mission M50 and V60 range of speakers? To me they seem exactly the same just look different and cost £50 more. But if you look the the specs on the Mission site (www.mission.co.uk) they are exactly the same, even the drivers/cones look the same. Has anyone heard/compared these speakers? Do the V60's sound better. Is it worth spending the extra £50 on the V60 if you prefer the look of the M50 range?
