Wow, yours are newer than I thought. I've had mine since fall of 2013. Initially I'll take a wait and see approach to see how the cubed versions are being received in comparison to the 2's but I suspect I'll go through with it. The problem with these big brutes is going to be shipping. I think James eluded to perhaps a 10% price hike so hopefully the upgrades won't be any more than 25% of the MSRP of the 2's. I still really want three 7's so perhaps my 1st introduction to the cubes will be via some 7's.
