" ....Why not keep your ML and add a 3channel amp for the additional channels?....."
+1 on this suggestion.
I use my hi-end Integrated amp as my 2- channel rig, and it also serves as the FL and FR channel amp as part of my HT.
-- I added a pair of hi-end separates (3-channel power amp and a matched 2-channel power amp) to a quality AV preamplifier /processor for HT.
-- I have a discreet hi-end CDP for my critical listening 2 channel audio and a separate BluRay player for HT entertainment .
