FWIW, I considered the Mac MA5200 too but could not find a 4 Ohm rating for its amp section anywhere on the internet and on Macs own website. In fact the back panel of the 5200 clearly states 8 Ohm by the speaker terminals. The Dyns you ordered are 4 Ohm and do love current, so you may want to rethink this one. Unless some 5200 owners can give assurances that it can properly drive your Dyns.
The title of your thread is asking about the Hegel H100. Now you state you need a DAC so you're looking at the H80? Have your needs changed since your original post?
If so, here's one to consider that may meet all your needs - the new Parasound Halo Integrated. More powerful than the H100 or Krell and with a built in Wolfson DAC. At $2500 its right in your budget.
