But quite a lot of what you need to understand in bench work is captured 
by a decent simulation, and a whole lot faster than you can capture it 
on the bench.

Simulations capture quite a lot of what is going on on the bench.

Sometimes the reality you have to deal with is easier to dig out of a 
well-set up simulation because you can fiddle with stuff in the 
simulation that you can't twiddle on the bench.

A great deal of electronic design is getting the right concepts 
together, and while bench work is usually a safer way of doing that, it 
can also be quite a lot slower.

The subjectivist audio people get quite sentimental about what their 
golden ears tell them. Peter Baxandall was an objectivist.
