Since I got my new denon receiver and calibrated it and tweaked it seems some low frequencies are more prominent than others. It seems like it is boosted so much in a couple of places in the low end. Could this be what "normal" sounds like? My room is weird and before some frequencies were a lot louder or quieter in the low end maybe the denon has altered this? As I'm sure it said it does something about room correction or something. Maybe the few odd frequencies were quieter but now louder than before and just sounds new to my ears. Any thoughts?
