There are any number of excellent amplifiers out there. The request for 'rack mount' is not necessary, as Middle Atlantic makes rack shelves with custom faces for anything you would reasonably purchase. So, you can go to McIntosh, or Emotiva, or Sonance or you name it for your amplification needs.
I would agree that you may not really need a equalizer anymore due to digital equalization being an integral part of modern A/V receivers.
