Ortho, I would suggest the Denon or Onkyo because both have the Audyssey MultEQ auto-calibration and room equalization circuitry, as you've already noted. Many(including me)view it as the most advanced system available in receivers at this time.
As to a choice between the 3311 and 3008, the 3008 should have a slight edge if you get get it at a similar price(e.g., Accessories4less), but a good deal on the 3311 might swing the balance. Either of these have amplifiers which should provide ample power for all safe(to your hearing)listening levels with your Axioms.
