In this segment, the presenter introduces the Raspberry Pi 3 as a single board computer used to create a network audio streamer. The device includes an ethernet input, onboard Wi-Fi, a DAC chip, and four USB outputs. The functionality as a network streamer is determined by the operating system on the micro SD card; in this case, Volumio is used due to its beginner-friendly interface and easy setup wizard. The video presupposes familiarity with a beginner’s guide to Raspberry Pi streaming. Volumio can be accessed via a web browser on any networked device and supports plugin options such as Spotify and Spotify Connect.

In this part of the video, the focus is on setting up Spotify Connect using Volumio on a Raspberry Pi. The presenter discusses the impending launch of Spotify’s lossless tier and aims to help newcomers set up high-quality audio streaming affordably. Specific hardware elements include various DACs and the Peachtree Nova 300 amplifier. The Raspberry Pi is shown running without its case for demonstration purposes, connected via Ethernet for network connectivity and analog output to the amplifier. The process of Spotify Connect is explained: selecting the Pi as an output device on the Spotify app, which allows direct streaming from the cloud even when the controlling device is turned off. The importance of gapless playback and the DAC capabilities of both the Raspberry Pi and Peachtree Nova 300 are highlighted.
00:06:00
In this part of the video, the presenter explains how to utilize a DAC (Digital-to-Analog Converter) with a Raspberry Pi to enhance audio output. They discuss using a USB cable to connect the Pi to an external DAC and configuring Volumio to change the output device to USB rather than analog. The presenter compares the sound quality of the DAC inside the Pi with the Peach Tree DAC, favoring the latter for its superior performance.
The video also introduces DAC HAT (Hardware Attached on Top) boards for the Raspberry Pi, specifically highlighting the Boss DAC board from Allo. These boards, which vary in price, connect to the 40-pin GPIO header on the Pi and handle digital audio conversion, resulting in a clearer audio output through analog ports.
Moreover, the presenter mentions using different HATs to alter the digital connectivity of the Pi, including a HAT that outputs S/PDIF or BNC instead of USB, providing more flexibility depending on user preferences or DAC capabilities. This segment emphasizes the various ways to enhance a Raspberry Pi’s audio capabilities using external DACs and HATs.

In this segment of the video, the speaker discusses setting up a network streamer with a Peachtree DAC using a coaxial input, emphasizing its cost-effectiveness compared to commercial network streamers. The setup costs around $180 for the network streamer and an additional $110-$130 for the DAC board and acrylic case. The segment includes a comparison between a Raspberry Pi 3 with an Audiophonics hat (costing about 90 euros) and other options, highlighting the hat’s ability to output digital audio via coaxial and Toslink. The speaker also evaluates sound quality, noting that while the Boss DAC board has good tone and substance, the Peachtree DAC offers better separation and transparency. The discussion ends with a preview of other DACs that outperform the Peachtree DAC and their integration with a Volumio Raspberry Pi network streaming system.
00:12:00
In this segment of the video, the speaker is discussing their use of a Raspberry Pi 4 with a heatsink case, connecting it to Spotify for music streaming via a USB DAC (AudioQuest Dragonfly Red). The Dragonfly Red DAC is responsible for converting the digital audio to analog, which is then fed into a Peachtree analog input. The speaker compares the audio quality of the Dragonfly Red with the Peachtree’s DAC, noting that the Dragonfly adds more soundstage depth and has a more dynamic sound. They then introduce the Helm Bolt DAC, which they previously showcased in an iOS/Android video, and connect it to the Raspberry Pi for further comparison.
00:15:00
In this part of the video, the presenter compares the Dragonfly Red and Helm Bolt DACs, highlighting the different qualities of each. The Helm Bolt is praised for its natural and organic sound, which is beneficial for less-than-stellar recordings and Spotify’s 320 kbps streaming. However, it lacks headroom compared to the Dragonfly Red, making the latter more suitable for quieter recordings like classical music. For louder contemporary music, the Helm Bolt suffices. Additionally, the presenter mentions the usability of both DACs with smartphones, noting the Helm Bolt’s less bulky nature. Moving on to pricing, the combination of devices adds up differently depending on the chosen DAC, with the Dragonfly Red setup being more expensive. Finally, the presenter introduces the Rasp DAC Mini from Audiophonics, a more advanced DAC with a built-in Pi 4, case, DAC board, and screen, which could influence the viewer’s decision.
00:18:00
In this part of the video, the speaker discusses a network streamer from Audiophonics that sells for about 180 euros (without the Raspberry Pi). Users need to build it themselves, but the instructions available on the Audiophonics website are detailed and clear. It requires a custom version of Volumio from Audiophonics, not the standard version. The screen on the device displays time, IP address, and volume settings, which is useful for those accessing it through the Volumio web interface.
The speaker highlights that Spotify Connect can be used with the device, displaying artist, album, track info, and a progress bar, though it does not support Roon. The complete setup with the Pi costs about 250 euros. The main advantages of this network streamer are its sound quality, which the speaker finds superior to previous setups discussed, and its smooth top end, deeper soundstage, and natural sound.
The speaker compares it favorably to the more expensive Volumio Primo but notes that the Audiophonics streamer may be replaced by a new model with a color screen. They encourage viewers to check the description box for additional information and updates on the product and emphasize using the comment section for community questions.
00:21:00
In this segment of the video, the speaker compares different audio streaming setups. They discuss the advantages and drawbacks of using a Xiaomi Mi Box S for Spotify Connect, noting that while it supports proper Spotify Connect, it has limitations like resampling audio streams to 48 kHz which can affect sound quality. The speaker suggests that for those seeking the best sound quality, the RaspDAC Mini from Audiophonics is a superior choice despite being less flexible than other options like the Helm Bolt or Dragonfly. The segment also briefly touches on the issues with Chromecast Spotify, such as lower bitrate limits and track gaps.
00:24:00
In this segment of the video, the speaker discusses the advantages of using Raspberry Pi for audio streaming, particularly noting its bit-perfect decoding at 44.1 kHz. They highlight that Raspberry Pi setups support high-resolution audio, though the focus is primarily on Spotify Connect in this context. The speaker emphasizes their preference for Raspberry Pi models, noting their compatibility and widespread use among hi-fi manufacturers, some of whom discreetly incorporate Pi hardware into their products. The segment extols Raspberry Pi’s affordability and versatility, encouraging viewers to experiment with these setups for their audio needs, prioritizing functionality over minor differences in DACs, and gradually focusing on sound quality through experience.
00:27:00
In this part of the video, the speaker encourages viewers to experiment with different operating systems like Volumio and find what works best for them. He invites the audience to take initiative in exploring these options. The speaker also asks viewers to like, dislike, or subscribe to his channel if they appreciate his approach to high-end audio and its integration with the Raspberry Pi. He concludes by expressing gratitude for the viewers’ support.
