From Astell&Kern 
A&futura is a premium line of players with advanced features that bring the original performance to life. The SE100, the first model of A&futura, is designed for you to feel the quality of premium Hi-Fi from the moment you hold it.

• Radically different sound by ES9038 Pro 8-channel DAC
• Next Level performance with Octa-core CPU
• 5-inch display with HD screen resolution and improved user interface
• Similar audio block design of SP1000 for premium Hi-Fi audio performance

A&futura SE100 shows our dedication to provide both premium quality and value to our listeners including an eye-catching design. It features a 5-inch touchscreen, Octa-core CPU, and the best audio performance in its league.Astell&Kern is committed to delivering the original performance as the artist intended you to hear and the SE100 is a symbolic example of this vision and effort.

A&futura SE100 introduces an 8-channel DAC chip. 8-channel DACs have previously only been available for premium home audio systems, pro-audio workstations, and recording studio equipment. It is making a debut for the first time in an Astell&Kern portable system. Your favorite tunes will now sound fundamentality different with even greater dynamic range and refined sound.

There are many audio companies that talk about 'technologies', yet Astell&Kern is the only brand that talks about 'progress' in the audio experience.

The ESS SABRE PRO series of Digital-to-Analog Converters (DAC) is targeted at premium audiophile and recording studio equipment. The SABRE PRO series sets a new benchmark in high-end audio by offering the industry's highest dynamic range (DNR) with impressively low levels of total harmonic distortion plus noise (THD+N) in a 32-bit, 8-channel DAC. All PRO SABRE DACs feature ESS's patented 32-bit HyperStream DAC technology which delivers outstanding sound quality and industry leading performance.

Maximum Output
It is common knowledge in the audio industry that the amplifier plays a critical role in Hi-Fi audio systems. The latest know-how and amplifier design technologies developed by Astell&Kern have brought 4.1Vrms of balanced output power with minimal noise. As the output power increases, the noise fluctuates louder as well. However, A&futura SE100 shows 123dB of SNR (Signal to Noise Ratio) at 4.1Vrms of audio output. At the same time, the noise level on single-ended is even smaller, it produces 122dB of SNR. Pure sound is the result in our technical achievement allowing for powerful, yet clean sound to be delivered gracefully by the SE100.

Femto-Second Clock for Exact Sonic Reproduction
An enhanced voltage-controlled crystal oscillator (VCXO) high-precision clock has been utilized in the A&futura SE100. The reference jitter of Astell&Kern's implementation has improved performance to 800fs (femto seconds), meaning that the SE100 faithfully reproduces your music by precisely measuring and accurately timing the synchronization of all instruments, vocal and even ambience sound recorded in your digital music file together.

Great Performance for the Ultimate Experience
The A&futura SE100 is equipped with an octa-core CPU which allows the player to produce the exact musical detail present in the original recording without distortion and provides a quick, lag-free operation.

The A&futura SE100 features faster booting times, speedy file transfers, lag-free processing and a new intuitive user interface for the ultimate player experience.

Ultimate Sound Quality
The A&futura SE100 supports native bit-to-bit DSD playback up to 11.2MHz for the best sound possible. The music is played back, bit-for-bit, just as the artist and engineer intended for it to be heard.

Faster Charging, Quicker File Transfer
Next generation USB Type-C support allows file transfer speeds up to 10Gbps and supports both data transfer and charging from the same cable. 

USB 3.0 protocol transfers data twice as fast when compared to other Astell&Kern players. Charging with a fast charger (at 9V/1.67A) takes only two hours and allows up to 11 hours of continuous playback.

* The maximum 11-hour continuous play is based on 16-bit/44 kHz, FLAC file format, screen off, 75 of volume playback.

From Astell&Kern 
A&norma sets the standard of Hi-Fi audio for novice listeners. The SR15, the first model of A&norma, is the beginning point of the Hi-Fi Audio experience that allows you to enjoy the philosophy and technologies of Astell&Kern, which is accoladed by audiophiles around the world.

• Dual DAC of CS43198, MasterHIFI™ tier chipsets from Cirrus Logic
• Enhanced audio processing power and snappy UI with Quad-core CPU
• Native DSD playback and playback-focused User Interface
• Powerful audio performance curated by Astell&Kern's know-how

The A&norma SR15 uses two audio DAC chips for a Dual-DAC setup. These chips are known for their use in Home Hi-Fi systems which offer greater presence compared to the inferior DAC chips designed for mobile devices.

There are many devices that use DAC chips for audio processing, however there are different tiers and quality of chips sought by Hi-Fi audio manufacturers to deliver an experience close to the original performance.

A&norma SR15 has adopted the MasterHIFI™ class DAC, CS43198 for the first time in a portable system. At Astell&Kern, we believe that true Hi-Fi should sound as close as possible to the original performance. The CS43198 is one of few DAC chipsets that is capable of bringing us even closer to the original when it's matched with the analog amp design of Astell&Kern. In result, it brings even more liveliness and warmth of sound without distortion.

Furthermore, A&norma SR15 supports native DSD bit-to-bit, and gets one step closer to the Hi-Fi system.

Cirrus Logic and Hi-Fi Audio Evolution
Cirrus Logic has built its reputation as an expert in audio IC (Integrated Circuit) chips and solutions for more than three decades and has established its distinguished recognition in the audio industry.

Specializing in low power ICs for audio and voice signal processing applications, Cirrus Logic's products span the entire audio signal chain, from capture to playback, providing innovative products for the world's top smartphones, tablets, digital headsets, wearables and emerging smart home applications. Now they have introduced the MasterHIFI™ chipset solutions for excellent audio reproduction performance.

MasterHiFI™ class designation is only given to their chipsets that meet their highest audio performance standard. It will deliver your music as the musicians and producers wanted you to hear it.

Enhanced Audio Processing Power with Quad-core CPU
Some may think that only sound matters in Hi-Fi systems. While it does matter greatly, there are other factors that influence your immersive music experience as well. A&norma is designed to remove any distracting elements, including noise, distortion and unintuitive user interface.

The Quad-core CPU gives you even more processing power for your digital music and a lot faster, natural UI experience. Get lost in your music without distractions.

• 24-bit, 192 kHz Bit-to-Bit Playback
• The A&norma SR15 plays any resolution of digital files up to 24-bit/192 kHz, bit-for-bit.
• For 32-bit audio, downsampling is performed by the SRC (Sample Rate Converter) method.
• DSD is native up to 64 MHz and DSD 128 MHz is converted to PCM for playback.

* 32-bit, 384 kHz is downsampled to 24-bit, 192 kHz, and 32-bit, 352 kHz is downsampled to 24-bit, 176 kHz for playback.
* DSD 128 is converted via DSD-to-PCM to PCM 24-bit, 176 kHz for playback.

USB Audio
A simple USB connection will allow the A&norma SR15 to be used as a digital music storage device and or pre-amp to output digital audio through USB. The A&norma SR15 transfers DSD in native format through DoP (DSD over PCM) and converts DSD to PCM for output for external USB Audio that do not support DoP.

* USB audio (Digital Out) output is available only when an external device can accept digital input through USB.
* DoP (DSD over PCM): This is the standard for transferring DSD data to a USB interface and sends DSD data by mounting them onto PCM data frames.
* The type of OTG cable to connect the SR15 with a portable amp differs depending on the specs of the amp. An OTG cable is not included in the SR15 package.

New Intuitive User Interface
A&norma SR15 has adopted the user interface of the A&ultima SP1000, which has grown famous for its intuitiveness and simplicity.

Our Take 
The Mojo might as well be the Bob Ross of the audiophile world: a true classic that everyone universally loves. If you want to get a taste of that iconic Chord Electronics sound and need a simple, no-compromises pocket-sized DAC/amp...gosh, you can't beat the Mojo.

From Chord Electronics 
Chord Electronics’ Mojo (Mobile Joy) digital to analog converter (DAC) and headphones amplifier create a new approach to high-end digital audio sound via headphones and in-ear monitors (IEMs). Chord’s Mojo magical “converter box” external DAC is as mobile as Apple’s iPhones, iPads or any Android smartphone, PC or pad. Chord’s mighty Mojo crystal clear audio is warm and detailed with soundstage breadth, and intimacy believed lost as analog-to-digital converters (ADC) gave way to digital-to-analog conversion.

Despite the small footprint of Chord's Mojo, Chord's new DAC only needs a few hours to charge. And your Mojo can keep rising for 10 hours continuous listening! Even better, thanks to a separate Micro USB charging port, you can charge and play Mojo at the same time. External power banks can also be used to charge Mojo on the move so long as they have a 1 amp output.

Advanced Design 
Designed and manufactured in England by Chord Electronics Mojo stands for 'Mobile Joy'. Chord says Mojo is a true reference-quality mobile DAC and high level headphone amplifier and Mojo's sound rivals DACs at twenty times the price. Chord's Mojo is also easy to operate. Mojo is devoid of bewildering number of switch options common on similar DACs.

Headphones 
Mojo drives any headphone between 4 ohms and 800 ohms (so most headphones). Mojo can drive two pairs of headphones simultaneously. Mojo works with any music file from 44.1kHz up to 768kHz and DoP DSD files: DSD 64; DSD 128 and DSD 256. 

Music Decoding 
Mojo can play all of today’s music formats. Mojo delivers breath-taking realism from digital music files such as: PCM; WAV; AAC; AIFF; MP3 and FLAC. Chord's Mojo works with smartphones and digital audio players. Mojo even covers specialist high-resolution formats such as DoP DSD files: DSD 64; DSD 128 and DSD 256. Mojo’s three high-resolution digital input options comprise optical (to 192kHz), plus Micro USB and RCA (mini-jack) which operate at up to an incredible 768kHz.

Fully Automatic 
Input selection is automatic: if more than one input is active they are prioritized as USB first, coax second, optical third. File frequency is shown by an indicator color option on the power switch, from 44.1kHz (red), 48kHz (orange) through a rainbow of colors to bright white for DSD.

The highly accurate low-distortion digital volume is controlled via two color-illuminated buttons. Many low-cost apps now make high-resolution music files playable from all smart phones. Mojo has three different high-resolution digital inputs: optical to 192kHz, plus USB and RCA (mini-jack) which operate up to 768kHz.

Advanced Battery Technology 
Mojo utilizes new advanced high-temperature battery technology. Benefits of advanced batteries include faster re-charging (up to 20 hours faster than competitive DAzCs). Mojo Charging is via a standard USB port. Mojo can play music while it charges. Mojo's charging Micro USB port has a battery status and charging indicator light. Mojo's casework is machined from solid aircraft-grade aluminum and has a hard Matt black fine finish that does not finger-mark. All inputs are denoted with a fine laser ablated permanent white lettering.

The first thing that came to mind when we first started testing the Micro iDSD Black Label was, "how is this thing only six hundred bucks?" This thing could easily sell for a thousand and still be considered a great value given its capabilities and sound quality.

If you have high quality or hi fidelity headphones you are going to need some power in the form of an amplifier to drive them to their true performance potential. You are also going to need an exceptional external HiFi Digital to Analog Converter or DAC to process your music files in high resolution to enhance your experience even further. The DACs in a smartphone, computer, tablet or audio player on the market are not designed for processing high quality sound. iFi audio has developed top of the line products to meet the various needs and preferences whether you are an everyday listener or an experienced audiophile.

 

The nano BL is a MQA compatible DAC and headphone amp that can be both portable or home based. At 285 mW max output power at 32R, it can drive almost any set of headphones without a problem. With it’s Burr Brown True Native Chipset, and added MQA rendering, you have even more file or format choices from MP3, DXD384, PCM384kHz, to DSD256.

With it’s S Balanced technology headphone channel separation is unchanged with load (requires balanced wired In Ear Monitors, also known as IEM, or over the ear headphones to benefit). Running a high-voltage Direct Drive Amp, the BL gets 3.5V into high impedance headphones making it suited even for 600 Ohm headphones. The built in iEMatch means it can drive high sensitivity headphones at 0.5V with a dynamic range that is virtually identical to that at "normal" output at 2V.

It is compatible with an Apple iPhone or Android smartphone and tablet, PC, Mac, desktop or laptop, and DAP (USB C adapter or cable is needed for some Macs and sold separately).
