Parasound Halo JC-1 Monoblock Break-in Period.

HI,
To all happy Parasound Halo JC-1 owners out there:
I was just wondering if the Parasound Halo JC-1's sound improves the most dramatically during the first 30 days of 24/7 signal, or during the second 30 day period of 24/7 signal?
What all sonic changes occur during the first 30 days?
What all sonic changes occur during the next 30 day period up to the 60 day mark?
How is the best way to determine that they are FULLY broken in?
Thanks for your insight.
