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. > learning by benchwork is slower because it is complicated by having to > deal with reality. 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. -- Bill Sloman, Sydney
