I think one of the problems is that often in most intermediate and undergrad electronics text books there is a tendacy to make things simple for the sake of explanations sake. Its 16 years since I was a
physics undergrad so I'm a bit rusty, but I can remember in many cases
there are often times when 'a bit of hand waving' goes on and we justify the removal of some difficult small term on the grounds that a factor x is << y therefore negligiable.Quite often this then gets taken to be 'gospel' and people don't look any deeper. As my old physics teacher used to say "it's in a book so it must be true.."
In most cases in lo-fi then they are possibly justified in this
assumption but if you are using good kit then these factors could be a part of the equation.What I posted was to say that these factors are real, in general understood and do have real world effects. In audio over a 5m length of cable they may be small and then it becomes an issue as to whether
the human ear can detect such subtle differnces. I personally believe it is possible although the effect is smaller than that of a better amp or speakers.

Steve
