Bel Canto E1X D250 Integrated Amplifier

The E1X D250 Integrated brings our Advanced Integrated Platform—rooted in the award-winning Black System—into a powerful, all-in-one component built for accuracy and control. Its HDR-II DAC core, AMiP architecture, optimized circuit paths, and software-controlled MM/MC phono stage work together to deliver clean gain, low noise, and exceptional clarity from every source, whether you’re streaming, spinning a CD, or playing vinyl.

The E1X Advanced Integrated Platform (AIP) pulls design elements from the award-winning Black System that optimizes both analog and digital system performance. Each input travels an expertly placed circuit path that provides noise rejection and signal optimization along with advanced custom time optimized filters that reduce sonic blur and increase clarity and dynamic impact.

The E1X D250 DAC/Control Integrated joins elements of our uncompromising technology in the E1X DC1 DAC with years of experience in power amplification to create a compact high-powered integrated component.

The E1X Integrated is without compromise taking full advantage of proprietary circuit design that includes the very advanced HDR-II (High Dynamic Range) DAC core and the AMiP (Asynchronous Multi Input Platform). Bel Canto technology and experience combines to provide uncompromised sound from any source, whether you’re streaming music through Ethernet or USB, using the full suite of digital inputs for spinning a CD, the line level inputs for a reel-to-reel tape deck or listening to vinyl via the internal MM/MC software controlled analog phono stage, you’ll experience the full potential from all source components.

The E1X D250 DAC/Control Integrated is designed to manage the complexity of all audio sources and control functions with ease and efficiency. The volume and system functions are controlled by manually pressing and rotating the control dial on the front of the unit, using the IR custom remote control, or with your iPhone/iPad and the custom iOS SEEK app. The E1X is also a Roon end point giving you the option to subscribe to Roon for network streaming to the Bel Canto platform. The fully programmable display is easy to read and illuminates system status indicating source and volume with auto off function when not in use. It also displays all programming functions.

All source inputs are asynchronously re-clocked into the fully balanced advanced segment DAC measuring below 0.001% distortion and 126dB of dynamic range. By stripping away the source clock and using Bel Canto’s custom Ultra Low Noise master clock circuitry we eliminate jitter and data related distortion, preserving the delicate audio signal.

Asynchronous ethernet connects you to the most compelling musical source available today. Bel Canto’s proprietary asynchronous ethernet and USB-A inputs provide the highest level of performance for high resolution files up to 24bits at 384ks/s, MQA, and DSD128. This allows you to connect to a variety of subscription streaming service or source from your personal library that is stored on a NAS (networked attached storage) drive, or an independent drive to the USB-A all providing server function with complete iOS wireless control using our SEEK control App. Android users can use the MConnect app.

Asynchronous Digital SPDIF AES, RCA and Toslink inputs all operate at 24/192Ks.

Asynchronous USB2.0 Audio is compatible with any PCM source up to 24/192 and DSD 64 (DoP). Windows-based computers require our custom driver. USB2.0 works natively in OSX.

MQA (Master Quality Authenticated) is an award-winning British technology that delivers the sound of the original master recording. The master MQA file is fully authenticated and is small enough to stream or download. Visit mqa.co.uk for more information. The MQA logo is a trade mark of MQA Limited. © MQA Limited 2017

RS232 is designed to support easy integration with sophisticated whole house control systems. The MM/MC phono section is a low noise, low distortion analog circuit that is fully programmable for optimum application with wide range of quality cartridges from high output MM 2.5mV to 5mV to low output MC 0.25mV to 0.5mV.

The line level analog input also can be programmed to gain match your analog sources and achieve the best performance from all analog sources. The line output can be connected to a powered subwoofer.

The front panel headphone jack opens up high quality sound for your favorite headphones. Plug in your headphones and the EX Integrated configures itself into a superb headphone amplifier with a buffer stage that can drive down to 32 ohms. Control the output level using the main control, allowing you to select the headphone or main speaker output while leaving the headphones in place.

Features: 

The HDR-II Core digital design starts with our Ultra-Low Phase Noise Master Clocks. These superior clocks are free running and fed from dedicated ultra-low noise analog power supply regulators. There are 2 stages of asynchronous interfacing to ensure that the final DAC output is jitter free and independent from any noise on the incoming digital signals. Our custom MQA based digital filters define an optimized impulse response from all sources, MQA, PCM, Analog and DSD. Figure 3 shows this impulse response with a 44.1kHz CD test signal. Our custom digital filters are designed to largely mimic the time domain response of an audio signal traveling through 10 meters of air. This superior time domain response insures the best sonic performance for all signals reproduced by our HDR-II Core DAC technology. MQA, High Bit Rate PCM, Analog and DSD all approach the impulse response resulting from travel through 10 meters of air, retaining the critical time relationships in the original music.

A critical advantage of our HDR-II Core architecture is how the Class A Differential Current Mode output from our DAC operates in concert with our custom balanced analog section to best preserve the original dynamics of the recording. The large constant-bias differential currents impose pure Class A operation to every part of the analog output stages, every precision resistor, film capacitor and amplification device is biased with constant current and voltage. This constant bias keeps all components in thermal stasis and insures that all the original signal dynamics are retained. Through careful parts choices, architectural considerations and design details, refined over numerous generations, Bel Canto’s HDR-II Core has been optimized to render pure, dynamic analog signal quality from all music sources.

Phono

Our analog dual stage phono architecture consists of an ultra-low noise input RIAA amplifier with precision filter components and fixed 40dB gain. This is followed by a digitally controlled analog variable gain stage to adapt the RIAA gain for a broad range of MM and MC cartridges. Input loading is controlled from the menu so that you can load your MC cartridge with the optimum impedance. This new phono architecture is optimized for accurate, low noise RIAA filter operation and compatibility with many cartridges.

Headphone Output

The Headphone output is driven from a dedicated 112dB dynamic range DAC through a high current output buffer stage. It can drive 32-ohm phones to high level and provide excellent headphone sonic detail and performance.

Sub Output

Bass Management functions include independent selection of a 2nd order Butterworth low pass and high pass filter set. The main speakers can be run full range or rolled off below frequencies from 40 to 120 Hz. The subwoofer low pass can be set for full range or frequencies from 40 to 120 Hz. This approach drives maximum flexibility to optimize the integration of a subwoofer. There is also +/-6dB of gain trim range on the subwoofer output.

Line Level Inputs

There are 2-line level analog inputs that provide 110dB of dynamic range and can be used for legacy analog sources such as tape, tuner or a home theater bypass where the volume level would be set to a high setting (84.0) on the ACI 600 and volume is controlled through the home theater processor. These inputs enhance the ability to integrate the E1X DAC into many different systems with many different signal sources.
