McIntosh Fans - I'm Considering an Amp Upgrade

I haven't posted here for a very long time. I'm finally getting all my audio gear back into use after over a year and a half of not having a decent listening room and must admit I'm greatly surprised at the superb sound quality in my new listening room. At the present time I have a McIntosh C712 Preamp, a MC2002 200 Watt Amp, MR-73 Tuner and an older Music Hall CD Player (soon to be replaced with a McIntosh CD/DVD/SACD player). I'm driving a pair of JM Lab 927BE Speakers that have superb mids and highs and more than adequate bass in my 11 X 14 listening room.
Mainly I would like to trade up my current amp for a MC7200, so I can take advantage of the balanced outputs on
my preamp and have also toyed with the idea of getting one of the latest versions (Mark V) of the MC275.
Your thoughts would be greatly appreciated about these possible upgrades
