Eric,

For what it's worth, you purchased one hell of a receiver with a power amp that performs extremely well with a ton of features, 3 years old or not & for a heck of good price. MCACC & Audyssey both have their strengths and weaknesses and quite frankly, IMHO are not the holy grail of purchase decisions.

I'm sure you will love the marantz sound for years to come. Don't look back on your decision and as JohnK says...enjoy the music, not the equipment.
