No, I don't plan on doing videos showing people how to master. What I want to focus on is things that will aid people to get a better sound quality from stuff they already have.

The first tutorial (about 50% done at this time) is on how to modify a "classic" studio headphone, the Beyerdynamic DT 770 Pro, to make it more balanced and to upgrade the quality of the cable. Another one I'll be working on is on how to make a passive, high quality switcher (for use with headphones or other line sources).

I do plan on making videos eventually, but probably geared towards mixing rather than mastering. I personally don't see the point in doing critical mastering processing over something like YouTube as the quality is less than great and there's also a huge difference in what I'm hearing from my DAC versus what you may hear over your laptop's headphone jack (chances are you won't be able to hear fine +/- changes over those kinds of DACs).

The only way to do something like that efficiently is if it were played back through a high definition format and I don't plan on getting into that sort of thing anytime soon.
