8 Advanced projects
called Amanero Combo386 module (more here:  amanero.com), a
USB class 2 to I2S 32bit and DSD output adapter.
1 Below is the list of parts you will need for the project:

1. A Raspberry Pi 4 with 4 or 8GB RAM
2. A microSD card with a special OS on it (Volumio, moOde audio or
Ropieee)
3. Amanero Combo386 HAT
4. DAC HAT (e.g. Ian Canada’s ES90382M dual mono II DAC HAT;
more here  ES9038Q2MP iDual Mono II Manual.pdf
5. A HAT for enabling music playback from multiple external sourc-
es, like a CD player, a DVD player (through HDMI input), or a TV
through SPDIF inputs (coaxial or optical input) (e.g. Ian Canada’s
ReceiverPi Pro HAT; more here:  ReceiverPi ProUserS Manual.pdf
6. A reclocker HAT (e.g. Ian Canada’s FiFoPi Q7, a flagship synchro-
nous mode I2S/DSD/DoP FIFO reclocker: more details are availa-
ble here:  FifoPi Q7 Manual.pdf
7. Better clocks for the reclocker HAT (e.g. Ian Canada’s SC-Pure
45.1584 MHz and SC-Pure 49.1520 MHz clocks; see here:  ScPure
Datasheet.pdf
8. Output stage HAT (e.g. Ian Canada’s LL1544A transformer I/V
HAT kit; see here for assembly:
 LL1544a Transformer I/V Guidance.pdf
9. A pair of good audio transformers to solder on output stage HAT
(e.g. Lundahl LL1544A transformers)
10. A Raspberry Pi HAT adapter station to further decrease EMI noise
and to separate Raspberry Pi and AUDIO HATs in two-stack con-
figuration with multiple separate power supplies for HATs (e.g.
Ian Canada’s StationPi Pro; see here for detailed assembly instruc-
tions:  StationPi Pro Users Manual.pdf
11. A power supply for powering the Raspberry Pi side of the Station-
Pi Pro (5V; we used a MCRU linear power supply; there are other
options, so feel free to do some research)
12. A power supply to power the audio side of the StationPi Pro (5V;
we used an ultracapacitor power supply designed by Ian Canada
named UcPure. As the name suggests you will need a pair of 3000F
capacitance ultracapacitors. The set-up is capable of delivering up
to 1000A dynamic current, so be very careful and do not just skim
