My hi-fi sounds great sometimes and not others.

Most likely causes would be your state of mind and your selection of
music
to listen to.

I am told that it
needs an hour's warm-up and this could fit with the times it has
sounded good.

If your system has some technical defect, then warming up could deal
with
the problem. In general audio systems are up to peak performance within
a
minute or less of commencment of use.

For example, great one evening but poor the next
morning.

Your system could have a defect that makes it extraordinarly sensitive
to
operating temperature.



More like changes in your hearing. Have you ever noticed that you set your
clock-radio in sleep mode and go to sleep listening to the news or
whatever
fairly quietly, but when it wakes you in the morning it is deafeningly
loud?

My ears are literally congealed in the morning. As the day wears on, they
loosen up.
The tissues of the ears live in a world of thick, goopy liquid, the
consistency of which varies from hour to hour and day to day.
