BAT VK-75SE or Rogue Zeus

Has anyone compared these two amps? I have the opportunity to get very good deals on either of these amps and wanted to know more about them. I have heard the BAT VK-75 and 75SE but not in the same system. The Zeus seems like a lotta amp for the money too and I will get to hear it in a few weeks at a friends home. I would probably use either amp to replace my Pass Labs X-250 on Talon Raven-C speakers and if I go with the Zeus. I will probably mate it to the M99 preamp, the BAT???
