I went to Bristol to listen to the non-upgraded and upgraded 861 and 7200's and I would say imho if it was a choice of the two I would have gone with the 7200 upgrade first. In fact that was the way I was going to proceed. However having had a quick demo at the same time... I upgraded the 7200's for 8000's. and can only say if you can afford/squeeze them in... Go for it, you won't regret it.
