NuPrime Stream 9X

NuPrime Stream 9X Network Streamer at Vinyl Sound Buffalo, NY USA The Stream 9X is a reference-class network streaming transport from NuPrime Audio (San Jose, California, USA), available at Vinyl Sound in Buffalo, NY, USA. Engineered for audiophiles who demand the highest digital signal integrity, the Stream 9X supports Wi-Fi streaming at up to 24-bit/192kHz, Bluetooth 5.0 with aptX HD, and a proprietary Sampling Rate Converter (SRC) capable of upsampling any source to PCM 24-bit/768kHz or DSD256 with ultra-low jitter. Roon Ready certified, the Stream 9X also supports AirPlay 2, Google Cast, Spotify Connect, Qobuz Connect, Tidal Connect, and DLNA, making it one of the most protocol-complete streaming transports available at Vinyl Sound's Buffalo, NY location. Multiple high-resolution digital outputs including IIS/DSD HDMI, AES/EBU, coaxial S/PDIF, and optical S/PDIF make it an ideal hub for any dedicated external DAC. Orbit Mini Streaming Module and Linear Power Supply At the heart of the Stream 9X sits NuPrime's proprietary Orbit Mini hi-res streaming module, purpose-built for network audio with dual-band 802.11b/g/n Wi-Fi (2.4GHz and 5GHz) and wired Ethernet via RJ45. This module handles full 24-bit/192kHz wireless streaming without compromise. Powering the entire circuit is a low-noise linear power supply (LPS), a deliberate engineering choice that distinguishes the Stream 9X from competitors relying on switching-mode supplies. The LPS suppresses noise at the source, maintaining an ultra-clean electrical environment for the streaming and conversion circuitry, which translates directly into a lower noise floor and improved audio transparency when feeding an external DAC. Proprietary Sampling Rate Converter: Beyond Standard Streaming Resolution The Stream 9X incorporates a NuPrime proprietary Sampling Rate Converter chip that surpasses what most network streamers offer. Any incoming digital signal, whether from a streaming service or a connected optical or coaxial S/PDIF input, can be upsampled or downsampled between PCM and DSD formats. The conversion path first upsamples to the megahertz domain before stepping down to the target rate, a technique that significantly reduces jitter and inter-modulation artifacts. The result is a stable, ultra-low-jitter digital output at rates up to PCM 24-bit/768kHz or DSD256, delivered over IIS/DSD HDMI or AES/EBU to a compatible external DAC such as the NuPrime DAC-9X. The SRC is selectable, allowing users to bypass it and pass through native source resolution when preferred. Key Features Wi-Fi Streaming at 24-bit/192kHz: Dual-band 802.11b/g/n wireless connectivity streams full hi-res audio without a wired connection, while a wired RJ45 Ethernet port is also available for maximum network stability. Bluetooth 5.0 with aptX HD: Qualcomm aptX HD Bluetooth supports 24-bit music quality over wireless, with a Bluetooth signal extender that extends range to beyond 30 metres. The Stream 9X receives Bluetooth audio from mobile devices but does not transmit to Bluetooth headphones or speakers. Roon Ready Certified: The Stream 9X is certified Roon Ready, functioning as a fully integrated endpoint within any Roon Core network for gapless, bit-perfect playback with complete library and DSP control. AirPlay 2 Support: Stream directly from iPhone, iPad, or Mac using AirPlay 2, and group the Stream 9X with other AirPlay 2 devices for synchronized multi-room playback throughout the home. Google Cast: Cast audio from Android devices, YouTube Music, or any Cast-enabled app, with support for hi-res streaming up to 96kHz/24-bit and multi-room grouping with Google Assistant voice control. Spotify Connect, Qobuz Connect, and Tidal Connect: Native integration with three leading streaming platforms allows the Stream 9X to receive streams directly from each service, bypassing the phone app for the highest quality signal path. Network DLNA and Libre Platform: Full DLNA network playback is supported alongside the Libre streaming platform, enabling access to local network libraries and NAS-hosted music collections. Multiple Digital Outputs: IIS/DSD HDMI and AES/EBU outputs carry PCM up to 768kHz/32-bit and DSD up to DSD256/DoP256. Optical and coaxial S/PDIF outputs handle PCM up to 192kHz and DoP-format DSD64 for broad DAC compatibility. Digital Inputs for External Sources: Optical and coaxial S/PDIF inputs accept PCM up to 192kHz and DoP-format DSD64, allowing the Stream 9X's SRC to process signals from CD transports or other digital sources alongside network streams. Go Control App: The free Go Control app for iOS and Android controls the Stream 9X, handles source selection, manages multi-room speaker grouping, and supports setup of compatible Libre and Omnia devices.

The NuPrime Stream 9X is a reference-class network streaming transport from NuPrime Audio, designed to deliver hi-res audio from streaming services and local networks to an external DAC. It supports Wi-Fi streaming at up to 24-bit/192kHz, Bluetooth 5.0 with aptX HD, and a proprietary onboard SRC capable of upsampling any source to PCM 768kHz or DSD256. Supported streaming protocols include Roon Ready, AirPlay 2, Google Cast, Spotify Connect, Qobuz Connect, Tidal Connect, and DLNA. How does the NuPrime Stream 9X compare to the Bluesound Node? The NuPrime Stream 9X operates as a pure digital transport with no onboard DAC or analogue outputs, while the Bluesound Node includes an internal DAC with analogue outputs for a more self-contained solution. The Stream 9X routes all audio through high-resolution digital connections including IIS/DSD HDMI, AES/EBU, optical, and coaxial S/PDIF to an external DAC, and its proprietary SRC upsamples sources to PCM 768kHz or DSD256, a capability the Node does not offer. Both units support AirPlay 2, Spotify Connect, Tidal Connect, Qobuz Connect, and Roon Ready, but the Stream 9X additionally supports Google Cast and the Libre streaming platform. The Stream 9X is built for systems where a dedicated external DAC such as the NuPrime DAC-9X is already part of the chain. Can the NuPrime Stream 9X stream audio to Bluetooth headphones? No, the NuPrime Stream 9X cannot transmit audio to Bluetooth headphones or speakers. Its Bluetooth 5.0 aptX HD connection is configured as an input only, meaning mobile devices can stream Bluetooth audio to the Stream 9X, but the unit cannot send audio out over Bluetooth. All audio outputs from the Stream 9X are digital: IIS/DSD HDMI, AES/EBU, coaxial S/PDIF, and optical S/PDIF. What is the Sampling Rate Converter (SRC) in the Stream 9X and should I use it? The Sampling Rate Converter (SRC) in the NuPrime Stream 9X is a proprietary NuPrime chip that upsamples any incoming digital signal, including network streams and connected S/PDIF sources, to a higher resolution before output. The SRC converts the signal to the megahertz domain first, then steps it down to the target rate with ultra-low jitter, reaching up to PCM 24-bit/768kHz or DSD256. The SRC is user-selectable, so it can be enabled to take advantage of the upsampling process or bypassed to pass native source resolution directly to the external DAC. Whether to use it depends on the capabilities of the connected DAC and personal listening preference. Is the NuPrime Stream 9X compatible with Roon? Yes, the NuPrime Stream 9X is certified Roon Ready. It functions as a fully integrated Roon endpoint, appearing natively in the Roon interface without additional configuration beyond connecting to the same network as the Roon Core. Roon users benefit from complete library management, DSP features, and gapless playback through the Stream 9X to any connected external DAC. What external DACs are compatible with the NuPrime Stream 9X? The NuPrime Stream 9X is designed to work with a wide range of external DACs. The IIS/DSD HDMI and AES/EBU outputs deliver the highest resolution signal, supporting PCM up to 768kHz/32-bit and DSD up to DSD256 or DoP256, making them ideal for high-end DACs such as the NuPrime DAC-9X that accept these connections. The optical and coaxial S/PDIF outputs handle PCM up to 192kHz and DoP-format DSD64, providing broad compatibility with DACs from Cambridge Audio, Chord Electronics, Topping, and others. The recommended pairing within the NuPrime ecosystem is the DAC-9X, which accepts all output types from the Stream 9X. Where can I buy the NuPrime Stream 9X in Buffalo, NY or the USA?
