Dynamics..

Now I'm craving soup.
Goldilocks says her porridge is too hot. If only she knew about ambient temperature and time constants.

Maybe she need an OD-3? But many say that creates soupy tone. I say let's ask Soupy Sales!

Sorry people, it's just been one of those days :crazy
 
Latency:
Latency is a simple, one-dimensional parameter that indicates the time delay between the input and output of a system.
Stated in an alternative way, latency is frequency-independent, whereas group delay is frequency-dependent.
Time Constant:
One of the basic laws of the universe is that many systems obey a first-order differential behavior.
It's more correct to state that first-order, linear mathematics can be used to approximate the behavior of some physical systems.

Incidentally thermal mass and thermal resistance are directly analogous to capacitance and resistance in an electric circuit and use the same symbols, R and C. One of the building blocks of electronic circuits is the RC network. It exhibits exponential decay with a time constant defined by R * C.
Here's an important relationship. In the case of an RC network as lowpass filter, R*C gives the rise time in response to a Heaviside step function, and the cutoff frequency is 1/(2*pi*R*C).

From the above it is clear that, for a system to have a long time constant - to be "slow" - it must have limited bandwidth. A first-order lowpass with a 20ms rise time has an upper cutoff frequency of 8 Hz. Clearly, circuit rise time is not a factor in whether an amp is perceived as "fast" or "slow."
 
Since this is a cold winter day an appropriate example is a bowl of soup. If we heat the soup up and then remove the heat source the soup cools rapidly at first and then more and more slowly as the temperature approaches the ambient temperature. The larger the volume of soup the greater its inertia or "thermal mass". The better insulated the container the greater the "thermal resistance". A quart of soup in a thermos will cool much slower than a cup of soup in a metal cup.
Interesting side detail about this is also that heat naturally always moves to cold (unless we force/interfere with stuff). Wether its conduction, convection or radiation. Just a side detail not relevant in this discussion, but knowing the basic laws of thermodynamics actually helps understandning several different everyday things in life that poeple usually never think about....
Or its just we HVAC people that like to think about things like that.
 
I was just trying to make a funny crosspost based on another thread.

We don't do that here!
