Luckily, we now have a selection of the best among them right here on Volumio shop. This article was written in 2014, and since then newer and better i2s DACs have emerged. Cheap yet good sounding setup: 80 bucks for a staggering price/quality combo.We’re not using the troublesome USB bus of the Raspberry PI, consider pop and clicks a thing from the past.Ideal signal path: shorter signal path and interfaces (USB, S/PDIF) avoided.But there’s more to come, to sum up and make it shorter, these are the main advantages of having a raspberry pi i2s DAC setup: I’m sure now you feel the truth deep in your heart, and the force is with you. Raspberry Pi -> I2S -> DAC -> Full-of-common-sense-amplifier Scenario 2: My little Raspberry Pi (you know what comes here…) has a tiny DAC hooked on it, via I2S connection, feeding my full-of-common-sense amplifier Quite a long way, isn’t it? Add to it all the intrinsic issues affecting connection interfaces, and you got quite a good idea of what is happening here. Raspberry Pi -> USB Bus -> USB Cable -> Zillion Dollar USB receiver -> I2S -> Zillion Dollar DAC -> Interstellar Amplifier My precious one and zeroes are facing this path: Scenario 1: My little Raspberry Pi (powered by Volumio, of course) is hooked up to a zillion dollar USB DAC, which feds my interstellar amplifier. And even if it was, an I2S direct connection has one great advantage: the signal path is shorter. I could also add that using USB as connection, in the Audio domain, is way far from being an ideal situation. Starting to smell why we are talking about this?Īs straight as we could be: I2S is the protocol of choice when talking about digital audio signal transmission. If it’s USB, i2s is the pathway from the USB receiver to the very DAC chip, if it’s S\PDIF the same as above. Most important, i2s is used also on every standalone DAC you may encounter. To better explain, i2s is used in all your fancy CD players, connecting the reading mechanism to the DAC and\or the S\PDIF output. The I 2S bus separates clock and serial data signals, resulting in a lower jitter than is typical of communications systems that recover the clock from the data stream. It is used to communicate PCM audio data between integrated circuits in an electronic device. I 2S, also known as Inter-IC Sound, Integrated Interchip Sound, or IIS, is an electrical serial bus interface standard used for connecting digital audio devices together. I2S is a communication protocol specifically designed to carry digital audio data. I may be aware there could be also other stuff worth of our joy, but this time I’ll concentrate only on that magic word, which audiophiles should have heard somewhere, sometime… So, what are we talking about? INTRODUCTION: WHY RASPBERRY PI I2S DAC IS THE RIGHT CHOICE There’s one thing better than a Raspberry PI, and this is an Raspberry Pi i2s DAC!
