>>841 I do not look down upon a person especially.
However, "death march" in knowledge labor becomes a problem now.
It is pointed out that a cause can demand a cause from ignorance for basics study.
The ability of an audio system lover was demanded to listening by a design.
There was wide understanding from engineering to art there.
If the reason why a person is absorbed is originally that there is
independent participation and is not so, people leave.
And people called an audio system lover were existence only as for criticizing it now,
and many people have left
What I wrote as liberal arts is because I explain that it is necessary
for an audio system lover to wear basics study to be able to cope
with broad knowledge about audio system immediately.
It is not a problem of a personal hobby to listen to an audio system.
It will be good with a cheap thing if I think with a problem of a so low dimension.
