![]() ![]() “The power requirements of the Raspberry Pi increase as you make use of the various interfaces on the Raspberry Pi. The 4B means your DAC choices are almost unlimited, as well as being faster to use and more future proof. Unless you are going to use a very air-flow restricted case, overheating shouldn’t be an issue, and adding a powered fan is an option (although this adds noise as well). The 4B model is about twice as expensive as the sub-$50 Pi 3B and 3B+ versions, but the improved speed and unrestricted bandwidth make the 4B this model of choice. While the 3B may be sufficient to run a network streamer device, the lower clock speed likely slows down the software and extends boot times. More on this later.Īlthough the 3B has the lowest power consumption of all the models, meaning it generates less heat, creates less thermal noise, and has the least chance of overheating, I don’t believe these benefits present a compelling argument to use this version. Clever folks worked around this limitation by designing separate DAC boards (HATs) that bypass the USB connection and connect via the 40-pin GPIO header on the Pi board. This combined controller restricts the bandwidth for USB-based DAC connections (to external DACs) and the Ethernet throughput. ![]() Pi Versionġ.2 GHz 64-bit quad-core ARM Cortex-A53 processorģ00Mbit/sec limited by shared USB 2.0 connectionīefore the 4B version, using a Pi as a network streamer was primarily limited by the shared Ethernet and USB controller. For the sake of this discussion, we only need to concern ourselves with the most recent Pi models. The Pi’s claim to fame is, of course, inexpensive and flexible open-sourced computing power. ![]() Each revision is more powerful than the previous but shares the same basic shape and size. There have been several Raspberry Pi revisions over the last few years. There are four main hardware components in a Pi-based network streamer: Build 2 does not include an internal DAC. ![]() Componentīuild 1 (left) contains an internal DAC so output analog RCA sockets were added to the rear cover. Build 1 (left) and Build 2 (right) with the Topping D10s DAC and xDuoo XD05 Plus DAC/amp.īuild 1 contains an internal DAC board but the slower Pi 3B+, while Build 2 does not include a DAC in the price (it requires an external USB DAC) and is based on the faster Pi 4B. These are fully functional and complete music streamers, but offer different options based on whether you already own an external USB DAC. I put together two recommended builds that are both priced around $250. The great thing about a Pi-based device is that you’ve got SO MANY options and choices to make every step of the way, and the end product can be significantly different for each builder. Your list of acceptable compromises is likely quite different than my own. Throughout this guide, I’ll explain what (and why) I selected for my own build, and I’ll also provide available options for you to make your own purchase decisions. I tried to select high-quality components firmly situated in the bang-for-the-buck category. With champagne tastes and my (cheap) beer budget firmly in mind, my frugality-fueled motivation was to see how fully-featured and high-fidelity a product I could create for the least amount of money possible. And the price CAN be far less than a finished commercial product with similar features and sound quality. It’s the ultimate DIY device, allowing the average tinkerer to select components and easily combine them into a custom product. Rather than using a multi-purpose, complicated, and inherently noisy computer to serve up digital music files, a Pi streamer can offer a streamlined and straightforward solution. Many compelling aspects of a Pi-based streamer became apparent when using the Streamer Ultra. My biggest takeaway from using a commercial Pi-based network music streamer was that I could build one myself! While I appreciated the device’s idea and sound quality, I struggled to justify the price and the compromises made in convenience and features. I recently reviewed the Orchard Audio PecanPi Streamer Ultra, a Raspberry Pi-based network music streamer device with an integrated touchscreen. I purchased all the components used in this guide. ![]()
