The Onkyo has dynamic EQ and the Denon has MultEQ. Thanks, because that led me to this site: http://www.audyssey.com/ where I can study it further.

I used to have the following system: Bose 901 speakers, Bose 250 wpc power amp, Soundcraftsmen pre-amp w/10 band per channel eq., Techniques turntable, Kenwood tuner. So I'm used to having a manually controlled equalizer. Not sure about the auto adjusting technology.
