McIntosh Intergraded

I am trying to decide between the MA-6100 or the MA-6200.I think the 6100 looks better. Can someone help me make up my mind? I use Cremona Auditors for speakers.

I believe the 6100 is 75w is that enough for my Auditors? The 6200 is 100w does the extra 25w wake a whole lot of difference ?

Do you have a suggestion for an intergraded with tone controls that will match my Auditors or speakers that would be a good match with the Mac? I am ready for a change.I'm using the Logos to push the Auditors sounds great but the quality of music I listen to needs help.Lots of 50's rock.

Thanks I will check on the Krell.I don't think punch is what I am looking for when it comes to listening to 50's.The recordings back then sometimes need a little extra bass or treble nothing to extreme.I always wanted to try vintage Mac who knows I might not like it.

Can the Mac 6100 play on 4 ohm speakers?
