I have denon 3311 and Pioneer 1222. Putting audessey out of the question there is no reason to take denon over pioneer. Advanced mcacc do a great job. You can tweak after calibration. Has 6 memory banks so you can leave one with original cal and copy that to another bank and do whatever you want With the copied cal without damaging the original. ( more bass, more highs, more or less mids, boost SW, etc).. Just one thing: crossover on pioneer is 50hz, 80hz, 100hz, 120hz, 150hz, 200hz and do it to alll speakers. On denon you can select xo to fronts different from center and from surrounds. Thats Pioneers philosophy. Also you will not have 60hz, 90hz, 110hz to cross over. Just those I mentioned.
