Two such options would be Pass or Ayre, but both are likely out of your price range.

Other entry level high power amp you may want to research

There is a couple discussions here on AG, that described the
Rogue Audio Cronus Magnum II Integrated Amp Combined with the MMG's sounding very good. I would think this would apply to the 1.7.
I think this is within your budget ($2,400.00 New) plus the pre is integrated. There's a fellow member by the name of mapman who wrote hearing this system. You could PM him to see if he could provide further info.   

Hi frog man,
Overwhelmingly high powered SS  amplifiers are suggested for driving Maggies.  I happen to agree with your recommendation if the objective is a more natural and realistic instrument/vocal tone. You've provided very good advice.

I have a Marantz PM8004 (stereo integrated) with my SMGa's and it has terrific dynamic range, beautiful tone and powerful, defined bass.

It seems to be a perfect match...
