Introduction
LinearPi MkII is a high quality audiophile grade manageable and expandable ultra low noise high current linear power supply. It could be the one of the greatest Linear power supply solution s for both digital and linear audio applications. Multiple LinearPi MkII s can be grouped into a whole power supply
system. LinearPi MkII can also be upgraded to ultra capacitor power supply by integrating with UcConditioner.

Specification s and Highlighted Features

  • 0.8uV Ultra low noise level
  • Ultra low output impedance
  • High speed high current low noise soft recovery Schottky rectifiers with option al shunt capacitors
  • Built in on/off control logic with on board or possible external on/off control switch
  • Multiple LinearPi MkII s can be grouped as a whole power supply system by making use of the built in isolated master/slave control signal chain.
  • Seamlessly integrates with UcConditioner to upgrade to an ultra capacitor power supply
  • Continuous AC input mode for best possible sound quality
  • Optional Kelvin sense input for better possible performance
  • Deal with MLCC piezoelectric effect noise
  • Double thickness 2oz PCB copper layer s for ultra lower ESR performance
  • Heavy duty fully SMT design

LinearPi Pro new features

  • 5A high current 3.3V/5V/12V high performance linear power supply 
  • Paralleling output stage for even lower output noise level
  • Ultra-low output impedance for great dynamic response
  • Much bigger heat sink to achieve to lower temperature at high current 
  • 29,000uF total filtering capacitance and high performance Schottky rectifiers
  • Four layer PCB optimized for low noise performance

LinearPi Pro 5V will be great for RaspberryPi 5 or other high current low noise applications. Recommend transformers: 1182Q6 or 1182L6(parallel coils)

Please reference the LinearPiMkII user's manual before formal release.

I like the whole concept as opportunity for music enthusiasts on a budget to build an audio dac/streamer for lesser price without compromising quality of sound. However, in my case I'm still struggling to get my streamer working built exclusively on Ian's parts. I suspect that Fifo Pi lost connectivity with other components. In my case dual mono dac hat and opa861. Monitor Pi shows no signal. In the meantime, I'm using pure pi and linear pi to power raspberry pi and different brand of dac hat and sound is awesome, clear, detailed and spacious like never before. Looking forward to fix fifoPi Q7 and keep upgrading.

High Quality LPS

Got the 3.3V and the 5.0V modules for my DDC and they works great. Recommended.

Ian is very supportive and this power supply complements his DAC boards. In fact, I am buying another set of boards along with the DAC power board.
