sridhar_125,
This is more than likely the "hit-and-miss" nature of the Denon auto-EQ/polarity circuit. Axiom gets frequent calls from owners of Denon, Yamaha, etc. that have the new auto-adjust circuitry.
These circuits are often erratic, especially the polarity and auto-EQ. Turn it off. Of course, check the polarity of your speaker connections, using the "Axiom" logo as a guide to keeping the positive connection consistent.
The auto-EQ should not be used. It has the potential to make linear, neutral speakers like Axioms sound bad.
You can try using the auto circuit for distance settings, but I think you'd be better off to do it all manually if some of the settings seem haywire.
In other respects, Denon receivers are excellent.
Regards,
