MPAudio - LT3045 based ultra low noise power supplies for audio application. 

LT4320 - The LT4320 is an "Ideal Diode Bridge" controller that drives four MOSFET's resulting reduced power dissipation and heat.

Quasimodo - Anti-transformer-ringing snubber: A snubber option, which makes it possible to significantly reduce transformer ringing.

All electronic devices need electrical power to work, usually delivered by a power supply with a very specific DC (direct current) voltage. An audio circuit's output signal consists to 100% of the supplied power (modulated by the input signal). That's why especially audio circuits / devices benefit of a stable and low noise power supply - the quality of delivered power can make a huge measureable and audible difference in your hifi-equipment.

​

Make the difference - that's what the HPULN Power Supplies are made for.
