I'm due a delivery of a Marantz CD6000 OSE LE to go with my PM7200 and SR4200, my tv shelves are full and so have my PM7200 on the ground beside them at the moment. I fully intend to get a decent rack - equinox or something - for the 3 units but in the mean time would it be a bad idea to have the PM7000 on top of the CD6000 or the other way round? I mean directly on top / below. I am guessing this is a big no-no but I have seen so many pictures of them placed this way. Would be for a month or so.
