Guitar amps should be designed at current rating of transformer. Part of the sound musicians like is due to thee higher voltage drop.
Home entertainment amps should have a low DCR for plenty of current reserve attributing to good voltage regulation. PP operating in Class AB or SE are most critical. I use approximately double the current rating.
I compared transformers into a LCLC filter not exceeding 100 ohms & use a low voltage drop rectifier such as a GZ34 or damper tubes. I compared that design to a shunt regulated that is as stiff a power supply one can achieve. Guess what, I hear no difference in-between the two power supplies. I also tried huge transmitter chokes at a combined 30 ohms. Again I hear no difference. Thus I do not require 30lb 8" x 8" x 10" chokes.
Some could argue my system is not detailed enough to hear the difference in microdynamics. I would tend to disagree with that.
