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 audible and measureable difference in your hifi-equipment.
Make the difference - that's what the HPULN Power Supplies are made for.
To provide clean and precise power to your audio-application
Power supplies and transformers perfectly matching your audio application
Different formats of "high performance ultralow noise" power supplies make it possible to choose a module matching the housing space or device's power need. With a variety of common used or individual voltages, MPAudio offers highest class transformers for your high end audio application.
The team of both, our power supplies and transformers, results in an easy to implement superb audible improvement.
