Hi Sooprman6,

Be cautious about considering the Integras or Onkyos if you are getting 4-ohm M80s. Tests of Onkyos continue to show that when 4-ohm loads are connected, the Onkyos will go into thermal current-limiting within a few seconds. This will severely limit your available power output to 50 watts per channel or less. Denon or H/K will drive 4-ohm loads without problems.

And think about some fabric wall-hangings or rugs to give to damp some of the reflections.
