I hope that you are referring to that if the amp is of "higher" quality
it will be more likely to have a longer shut down time. I think that
Patrick B. explains my thinking of this pretty well:
<<It has everything to do with the circuitry in the amp. All amps take
longer to power on than your head unit, as they are a more complicated
cicuit. I would even venture to say that the more high quality and high
powered your amp is, the longer this lag will be.

I think you are right on the money, Patrick.
OK why would it take an amp longer to shut down because it has internal
capacitors. These caps store power for the power lead, which in turn draws
power from the charging system. As far as I know, the remote wire serves to
supply voltage in order to turn the amplifier on. It does not draw current
from this source the same way the + lead does. So therefore if the amp is
no longer getting a turn on signal when the HU is turned off, the internal
caps are not going to be able to provide the amplifier power because the
amp is no longer on!
As to the whole "I would even venture to say that the more high quality
and high powered your amp is, the longer this lag will be". why would this
be true, what does quality have to do with this "lag"? The power rating
might have an effect, since higher power amps usually have more internal
capacitance. But a good brand name means nothing in this area! A close
friend of mine has a $20,000 system consisting of 4 Phaze Audio tube
drivers, his system has turn on/off noise! This thump is not a bad thing,
it's a matter of personal preference. If you don't want to hear it, then
either buy amps that have built in delay circuits or build your own delay
circuit! It's a matter of manufacturer design! Not a matter of how high
quality it is!
