This 90D kit combines three complementary modules from Ian Canada: a PurePi II hybrid power supply, a TransportPi Digi II reclocked digital interface, and a MonitorPi Pro control centre, forming a high-performance platform that only requires the addition of a Raspberry Pi to create a fully operational audiophile network player.
This kit does not include a Raspberry Pi or LiFePO4 battery; these are available as accessories.
The MonitorPi Pro features a 1.54" OLED display and a high-speed digital analyser that scans I²S/DSD signals up to 128 MHz in real time, instantly displaying the detected audio format (PCM up to 1536 kHz, DSD up to 1024). This driverless Linux architecture connects directly to the Raspberry Pi's GPIO, exposing playback metadata and digital chain status without additional processor load. The module incorporates dedicated controllers, centralising system management via a physical button or IR remote control.


The PurePi II delivers two isolated rails: 5V via supercapacitors for the Raspberry Pi, and 3.3V via LifePO4 battery for audio peripherals. This passive architecture eliminates high-frequency noise from switching power supplies, with the supercapacitor rail allowing current transients without active regulation, while the battery ensures stable impedance for clocks and analogue stages. The SYNC charging function recharges the batteries during breaks, extending battery life.
The TransportPi Digi II extracts the I²S streams from the Raspberry Pi, reclocks them via femtosecond clocks (45.1584/49.1520MHz) and distributes the signal to four simultaneous outputs: isolated coaxial/optical SPDIF, I²S via HDMI and GPIO. Proprietary discrete reclocking (3 stages 1-bit for SPDIF, 2 stages multi-bit for I²S) eliminates jitter inherited from the Pi. The direct 3.3V input bypasses the integrated regulator, allowing the injection of an ultra-clean rail from LifePO4 batteries.
