Just to add one note on another correction method - I have a Pioneer receiver with the MCACC. I also let it do it's thing, but then turn off the EQ setting it comes up with as I also find the sound is just 'thinner' with the EQ engaged. I do however find the standing wave correction improves things in my room.
