The 7005 doesn't use MultEQ, it uses MultEQ XT, though I don't know if your research still would lead to the same conclusion or not. FWIW, it's not a small difference, as it is up to an 800% increase in filter resolution between these two techs. Of course if he was willing to consider Denon or Onkyo, he could go up to the XT32, and if willing to buy a pro kit (or hire someone), he could land a Audyssey Pro capable unit.
