I'd agree and - IME - extend that statement to dedicated rooms.
I've had professionally designed, heavily treated, dedicated theater AND two channel rooms in each of my last two homes. (Due in large part to Kal's observations), I tried Audyssey in each room. Others may disagree, but I found it a 4 for 4, 100% no-brainer. Everyone's got different priorities, but I regard any trade-off in transparency (in both theater and two-channel rooms) as trivial relative to the overall sonic improvement - particularly in the bottom two + octaves.
