How a toroidal transformer is wound

I always wondered how they wound toroids. Here is a link to a video of that process.

Like the ones in my DS Audio E1 equalizer and Esoteric DAC. Although I guess there are strong arguments for any type transformer whether it be Toroid, R-core, laminated core, isolation laminated core, and whatever.

Each type has its posotive and negative characteristics. The R core seems to have the lowest radiated energy and less input current rush than toroids. The toroids seem to be the most efficient.

Here is how an R core transformer is wound. It is interesting to note that since the core cross section is round compared to rectangular as with a toroid, the bobbins rotate on the core during winding. There are also O cores.
