Maybe they could update MCACC to eq subs much better and match XT32. They could release 100 models, but I will never buy another one until they do.
Room correction is nice and all, yet with MCACC you can tweak it far more once it is done. EQing subs is great and all but it is a job easily done by yourself and is rewarding, with an added bonus of learning more about the receiver and settings. Room correction holds your hand but I always tweak it once it is done, I have yet to have room correction get everything 100% where I want it or like it.
The bonus of MCACC is that it allows you to tweak it more than Audessey, which is why I prefer it greatly.
