Hi. Thanks for comment. Sorry I didn't do that in the beginning because I put this video just to show one of my client how his Moode player is build. I will try to make step by step instructions in future .TQ
Very nice indeed! I have a RPi3 with the HiFi Berry Digi+ Pro. I use the optical out directly into my Kanto YU3's Sounds really good but the current standard RPi power adaptor ("wall wart") would benefit from an upgrade. Plus, I wonder if all the unused circuitry on the RPi might be causing unnecessary noise and needs simplifying too?
Linear power do really make huge difference especially if you are using low noise regulator. Toroidal and R-core has lower magnetic leakage and sure it performed slightly better than normal EI core transformer. I used EI core transformer just because of I built this for one of my customer who request for a lower cost EI transformer.
A LPS only makes sense for analog data, e.g. for the amp which produces an analog output signal. It is useless for a computer which produces a digital output signal. Digital data is digital data, nothing else. But there is a whole industry out there to tell you something different and to sell you uselsess stuff. It's up to you what you believe - and not my wallet.

Hi, I'm satisfied with its sound quality, you need to use 2 linear power supply to sound good. One for raspberry Pi, and another one for the WM8805 board. please modified the WM8805 board by separate its power supply from Raspberry Pi so that you can supply it individually. I used this mainly just for playing music file stored in USB pen drive. Please make sure your file format are uncompressed WAV file, I tried FLAC and compare with WAV, and WAV file sound much better. You need to pair it with good DAC of your choice though, I built this just to replace my old CD transport. In fact, I already built 4 units for my others audiophile friends, you can find other build video in my channel. Please tweak your Raspbery Pi's config.txt as shown in my web page to underclock the raspberry pi a little, although the tweak slow down the processor, but noise had been reduced and sound quality improved. Hope this help.
@@fibranijevidra Hi. , as mentioned earlier, the internal power supply produce much lower noise when underclock a little. those noise can interfere the I2S signals. Digital noise is very bad for DACs . I can post a new video of the noise level comparison when I find time. Pi Zero is not suitable for new build now, because of most OS for music player already upgraded to higher version which require higher processing power.
It would be nice if you explained anything about what were you adding or at least a list of components used.

Do these power supplies compared to the wall wart ones REALLY make a difference and if they do then surely you should be using a tordial transfomer?

you need to modified the I2S to SPDIF board to sound good, by disconnect power supply in between Pi and I2S - SPDIF board, and feed individual 5V from your regulator board,one for Pi and one for the I2S to SPDIF board.
also, I'm using Pi zero without wifi because I'm using metal casing, wifi should be install outside the metal case so I use USB wifi dongle. I use USB drive to store all my files and play via USB.
