Allen,
That's a great way to explain the need for a choke-input. I started using choke-input supplies for B+ (most with subsequent regulators) almost exclusively in years past (back when I had time to build things). The elimination of those huge magnetic field spikes adds a certain ease to the sound. And no matter how robust one's ground wiring is, huge current spikes will create voltage pulses in the ground system.
