The X-Stream 9 from Advance Paris is a multifunction device that brings together a network player, a digital-to-analog converter, a CD player, and a radio tuner in a single chassis. It is designed to handle both digital sources and physical media, serving as the central component in a modern hi-fi setup.
Technical Architecture and Precision Digital Conversion
At the heart of the X-Stream 9 is the AK4490 converter from Asahi Kasei Microdevices, the central element of the device. This 32-bit DAC is based on AKM’s VELVET SOUND architecture, a technology adopted by many manufacturers specializing in high-resolution audio. This architecture is characterized by an exceptionally low distortion level (-112 dB) and a signal-to-noise ratio exceeding 120 dB, allowing the most subtle details of recordings to be revealed.
The converter supports PCM signals up to 768 kHz and DSD streams up to 11.2 MHz, thus covering all current high-definition formats. Five built-in digital filters allow you to optimize the sound according to listening preferences and music type. The audio output stage has been given special attention, with circuits optimized to preserve the integrity of the reconstructed analog signal.
Integrated CD Player: Tradition Serving Modernity
Despite the rise of streaming, the compact disc remains present in many music collections. The X-Stream 9 features a CD player equipped with the latest generation Tamul servo mechanism, ensuring stable and precise playback. The technical solution combines a 16-bit processor and a 24-bit DSP, enabling playback of CD, CD-R/RW, and CD-DA formats (including burned MP3 and WMA files).
This reading mechanism benefits from a robust design, ensuring reliable long-term operation. The centrally positioned loading tray, harmoniously integrated into the methacrylate front panel, reflects the aesthetic balance that characterizes Advance Paris products.
Network and Streaming Capabilities: Embracing the Digital World
The X-Stream 9’s network section is built around dual 2.4 GHz Wi-Fi and Ethernet controllers, offering flexible connectivity for any setup. Compatible with DLNA and AirPlay protocols, the device integrates seamlessly into the home digital ecosystem.
The Advance Playstream app, available on iOS and Android, is the preferred control interface for accessing streaming services. Spotify, Qobuz, Tidal, Deezer: all major platforms are natively supported. In addition, several thousand internet radio stations from around the world are available, greatly expanding your musical horizons. Spotify Connect compatibility also allows you to use the service’s native app to control playback directly.
Comprehensive Connectivity for Universal Integration
The X-Stream 9 stands out for its extensive connectivity. On the digital side, there are three optical and two coaxial inputs, complemented by their respective outputs for daisy-chaining to other devices. The USB-B input features an XMOS XU208-256 controller, a chip renowned for its performance in asynchronous mode. This 32-bit/8-core interface allows direct connection to a PC or Mac, with native support for all high-resolution formats up to DSD.
A front USB-A port accepts flash drives and hard drives for direct audio file playback. Analog outputs are available in both balanced (XLR) and unbalanced (RCA) versions, with output levels of 4 V and 2 V respectively. This dual configuration allows optimal adaptation to the amplifier in use.
Trigger and infrared connections make integration into a home automation system or complex audio setup easy. The BDD (Bluetooth Direct Digital) port allows optional addition of the X-FTB01 module, providing Bluetooth connectivity with aptX codec for CD-quality wireless transmission.
FM and DAB+ Tuner: Radio in All Its Forms
The X-Stream 9 features a triple FM/DAB/DAB+ tuner, continuing the tradition of terrestrial radio while embracing digital broadcasting. Reception sensitivity is particularly effective, even in challenging conditions. Station memory and navigation between presets are intuitive, whether using the remote control or the front panel interface.
Preamplifier Mode: Flexible Use
Beyond its primary function as a source, the X-Stream 9 can be configured in variable output mode, turning it into a preamplifier. This feature allows direct connection to a power amplifier or active speakers, with volume control managed from the device or its remote. This versatility meets the evolving needs of an audio system, allowing for various configurations as required.
