I just tried 4 of Charles Neil's videos and they sounded fine on my Kindle and computer.
It is interesting reading this thread and the viewpoints. Several commenting are those who are making and finishing projects for sale and doing quantity finishing. For them it seems that time, cost, and visual appeal are all important.
In my case, I am only interested in how it looks and have a lot of time to finish a project. The difference in cost for me is negligible and I am only doing one project at a time. I often will take a week to try different finishing regimes to see what I like best. Also, I have no interest in developing my own secret recipe for finishing.
