I haven't received the new amp yet (got it for $499 on Newegg), so I am wondering, what improvements have been made to MCACC in the last two years, specifically between these two models? I did notice that the description of the 1222k states that it measures speaker distances down to the inch, whereas the 1020k only did 1/2 foot measurements. So, are people finding MCACC to give more accurate results on the 2012 models?
Pmanyon, I hate to be the one to say it, but I will: don't be surprised if you hear little or no difference between the two receivers. The difference in output power is likely to be significant only under very extreme circumstances (such as running 4 ohm speakers) if ever, and MCACC is essentially unchanged.
Certainly it has several useful features that may make it a worthwhile upgrade, but if your concern was that the old AVR was very underpowered for your combination of room and speakers, this isn't the degree of an upgrade that's likely to correct that. Remember, it takes a doubling of output power to produce just a 3dB increase in SPL, and in practical terms the 1020 and the 1222 are similar in power output.
Of course, the SC1222 does have pre-outs, so you can always add external power amps that really can solve the low-power problem, so it's a useful step towards future upgrades.
