Mcintosh MA7000 vs MC402/C46 combo?

Matt, thanks for your opinion.
I don't have the option of the 402.
I just want an opinion on ma7000 vs mc402, whether to accept the trade offer or not. 
The items to trade for (my items) are a Hegel h300 and a Unison Research S6 vs the Mac (offered).

I think it would be a lateral move at best. 

greginnh,
a lateral move suits me fine in this situation. if it IS a lateral move.

A new development in my options - an MA6700 was offered as a substitute for the MA7000. I have educated myself on the set of features this integrated offers, my question is about its sonics: how does it compare to the MC402 line?
I'd really appreciate some practical advice here.
Thanks in advance!

Mc402 is nice, big sound, lots of dynamic headroom.
