If we put larger and larger bulk capacitance we can end up with extremely high peak and RMS currents through the input bridge and the filter chokes (along with a lot of low frequency harmonic content ...

Power Supply: Full dual mono, choke input, 2 48VA transformers, and 2 chokes, separate 100V front end rail for each channel, 100% discrete regulation with over 20,000uF filter capacitance per channel.
