Do an R-core for:
Have you ever touched a toroidal transformer and felt the vibration? R-cores are famous for being mechanically silent. The continuous grain-oriented core and the even distribution of windings eliminate the magnetostriction that causes that annoying 120Hz buzz. For a listening room with quiet acoustic tracks, this is a massive quality-of-life improvement.

Because the primary and secondary windings are physically separated (not overlapping), the inter-winding capacitance is drastically reduced. This means high-frequency noise from the AC mains has a much harder time capacitively coupling into your secondary (clean) side. For phono preamps, DACs, and headphone amplifiers, this translates to a blacker background.
