5V - 19V regulation is often done through induction coil transformer. Normally, it's ideal to have 7V output from transformer and regulate 7V output. Nikola uses different transformer for matching output voltage unlike other companies that use 19V output and regulate 5V.

R-Core transformer is often used in analog equipment for high current output with more power in compact size. I haven't seen any company producing highend digital equipment using R-core transformer though.

Toroidal transformer is often used in digital equipment for linear power supply. For example, Esoteric uses that for every models. Other highend companies producing digital equipment like dCS/Emm Labs will use switching power supply as an alternative.

To get the same power output using toroidal transformer, it'll be bigger than R-core. Since you seems interested in HDPlex product, I won't comment further about its design principles as that isn't appropriate in my position to say more than that.
