I have listened to the ms package and while good for a small room wouldnt do justice to your amp more a pairing with the 16xx or 188xx. In you room and for stereo go for some fullr ange standmounters or floorstanders as any sub sat package no matter how goo will still leave that mid-bass hole.
the sub on the ms old ones was ropey I have not heard the plus system if you want compact speakers look at some kef eggs or the b&w vm-1. If youre budget and size is limited the MS package may be the best off the ones mentioned.
Good system, superb sub but prob not bigenough to really fill your room. Use the 302's as surrounds and buy 904/906/908's as your front speakers. Instant 7 speaker system that is totally tonally the same and looks fantastic
I have the spec as in my signature and it sounds really nice to my ears. I would go with the m7 series, as they're discontinued you can probably pick them up really cheaply now. I think I'm going to use my new found income to buy a nice new pair of front speakers (probably something of a mission flavour) and use the m72s that I have atm as rears.
