Holo Audio – RED Network Streamer & DDC
Premium Digital Connectivity
The HoloAudio RED is a versatile network streamer with I²S HDMI output supporting DSD playback up to DSD1024. It also functions as a digital-to-digital converter (DDC), allowing conversion from USB to I²S or SPDIF.
DDC Mode: To activate, power the RED on with a USB source connected. Streamer Mode: To return to streaming, disconnect the USB source and reboot the RED.
A critical part of the HoloAudio RED’s performance is its dedicated linear power supply, designed specifically for audio applications. Unlike common switch-mode power supplies, the RED’s linear design delivers clean, stable, and low-noise power, which is essential for preserving signal integrity in digital audio playback. The HoloAudio RED is housed in a chassis that is milled from a single solid block of aluminum. The result is a component that combines audiophile-grade performance with robust durability, ensuring that the RED operates in an environment free from unwanted interference. This meticulous attention to mechanical engineering complements the advanced electronics inside, allowing the RED to perform at the highest possible level.
At its core, the RED uses a Pi Compute Module 4, but unlike a standard Raspberry Pi, this version has been custom-developed by HoloAudio and optimized for high-end audio. By removing unnecessary peripherals and tailoring the design for sound quality, HoloAudio ensures both performance and flexibility. The RED remains highly versatile thanks to its broad software compatibility.
Roon Ready & Audirvana Certified: The Ultimate Streaming Bridge

Holo Audio RED - Reviews & Awards
Holo Audio
When people talk about innovation in high-end audio, the name Holo Audio often comes up. Behind the brand stands Jeff Zhu, a designer whose vision has helped redefine what digital-to-analog conversion can be.
Jeff Zhu’s journey into audio began with a passion for music and engineering. While many manufacturers follow wellworn paths in digital audio design, Jeff believed there was room for something more radicaln approach that combined cutting-edge engineering with the natural warmth and presence music lovers crave.
That philosophy led to the creation of Holo Audio, a company that quickly gained worldwide recognition. The Spring DAC and May DAC series put Holo Audio firmly on the map, introducing the world to discrete R2R DAC designs and groundbreaking technologies such as true linear compensation. These innovations solved long-standing problems in digital playback, allowing Holo Audio products to reproduce music with remarkable accuracy, texture, and emotional impact.
But beyond the technical achievements, Jeff Zhu’s work reflects a deeper philosophy: audio gear should serve the music, not the other way around. Every Holo Audio product is built with this principle in mind, balancing advanced engineering with a focus on musicality, craftsmanship, and longevity.
Today, Holo Audio continues to expand its reputation across the globe. With Jeff Zhu at the helm, the company remains committed to pushing the boundaries of what’s possible in digital audio, while staying true to the simple goal that started it all: helping people connect more deeply with the music they love.
Tim Connor has many years of experience in the Audio Industry and is passionate about just enjoying the music. He strives to exceed your expectations by helping you choose the right products that fit best for your needs. Please contact him with any questions you may have. His wife, Dawn Connor, is also very passionate about music, and sang in Choir for many years. She enjoys learning about and working on electronics, (including past experience with guitar equipment) audio grade, and higher specification, wiring and the founder of KitsuneHifi.
In the world of audio equipment, wires are the staple of life as they are required to transfer electricity, the more strands the better conductivity and electricity transferred more efficiently. As with a wise kitsuné, the more skilled and knowledgeable the craftsman the better the end result.
At KitsunéHiFi we’re always searching for the mythical creature… the awe inspiring equipment of legends.
The kitsuné logo was inspired by a few things, a bedside lamp with a cute little fox, the fox-spirit from Never Alone (Kisima Ingitchuna) (which Dawn kept calling a kitsuné), and our pup which looks a lot like a little fox and credited in part to the Kitsuné head logo
