From Astell&Kern
The SR25 is the second model in the Astell&Kern A&norma standard line. Beginning with the AK70, Astell&Kern's goal was to bring high resolution audio and the Astell&Kern sound to more music lovers. This goal continued with the successor to the AK70, the A&norma SR15, and now evolves further as the SR25, a premium product that fully embraces Astell&Kern's philosophy and technology, now available to the masses. The SR25 is the latest answer to our never-ending question of "How do we get closer to the original sound the artist intended?" 

The SR25 improves on the SR15 by:

• Adding a new, faster Quad-Core CPU paired with the Dual Cirrus Logic CS43198 Master Hi-Fi level DAC, first used on the SR15
• Native playback support for DSD256
• A new class-leading performance mode for ultra-high quality playback without compromise
• Newly designed circuitry to improve sound quality enhancements
• Addition of Bluetooth LDAC codec to give users more options for higher quality wireless sound
• The essence of Astell&Kern's philosophy that sound quality is never compromised is exemplified in the SR25, which expresses every musical detail and bit-perfect playback as only Astell&Kern can. 
   

Performance Mode for Ultra High Resolution Sound

The SR25 supports native DSD256 and 32bit/384kHz audio for the first time in an Astell&Kern standard product and boasts performance that cannot be compared with other competitors' products.

The SR25, which is smaller than other players, has been developed to achieve stable, ultra-high resolution sound. We have developed a new Performance Mode with the SR25 that automatically optimizes and sets the memory mode in the system according to the data size of the source being played.

As the resolution of the sound source increases, it is necessary to process a large amount of data rapidly. If this part is not optimized, sound breakup may occur. To prevent this, the SR25 uses the new Performance Mode to adjust and optimize the system in order to produce near perfect sound quality when playing back high resolution audio.

Experience ultra-high resolution with the SR25's Performance Mode, which reproduces even the smallest, minute details of the original recording the artist was looking for, without compromise.

Perfect Circuit Design for the Highest Sound Quality

Proper playback of DSD256 and 32bit/384kHz digital audio requires a high-performance CPU and fast memory speed, along with an audio path suitable for high-speed signal processing.

Optimizing the length of the audio path is a very important part, as failing to properly do so can create a time delay between the signals resulting in sound abnormalities.

With the SR25, the Astell&Kern team developed a completely different PCB design from the existing SR15 to process the high speed signals where required, resulting in audio path lengths that are the same, allowing for super-high resolution sound without any delay.
Furthermore, newly designed audio patterns and power circuits for distortion-free signal transmission and noise rejection are applied to each channel.

The result is an Ultra Low Noise Filter that allows you experience Astell&Kern's flawless sound, with Zero Noise, on the SR25.

Embark on a Musical Journey That Lasts the Entire Day

If the power supply's stable design and efficiency are not properly taken into consideration, the input/output voltage difference becomes large, and when the output current is large, the output voltage can become unstable. This leads to excessive noise being generated, which can be a major cause of poor sound quality. In addition, poor power efficiency will result in a shorter playback time.

The SR25 set a big challenge for the Astell&Kern engineering team – add the longest playback time of any previous Astell&Kern product, while maintaining the signature Astell&Kern quality sound, and a low-noise floor.
In the SR25, the team not only applied highly efficient components, but they focused on developing circuit optimizations to get the most out of their performance.
The result is up to 21 hours of continuous play time, more than double the previous generation SR15, with no compromise in sound quality.

No need to worry about battery life while on your daily journey, just have fun on your Music Trip with the SR25.

Continuous Playback Time

* Standard - MUSIC: FLAC, 16-bit/44.1kHz, Unbalance, Volume 80, EQ OFF, LCD OFF

No Compromise on Sound, Even When Connected Wirelessly

In addition to 24-bit music playback via aptX^TM HD Bluetooth as in previous Astell&Kern players, the SR25 adds LDAC support to give users more options to listen to high resolution audio wirelessly.

Now you can enjoy Astell&Kern's high-quality sound when paired to Bluetooth earphones, headphones and speakers.

Astell&Kern's Exclusive Metalworking Technology

Astell&Kern products are often compared to art sculptures, with colorful faces and angles not found in other products. This precise design work is based on Astell&Kern's long accumulated know-how and highly precise metalworking technology.

In order to produce this unique style Astell&Kern is famous for, 5-axis machining is performed instead of traditional 3-axis machining used in general machining. All metal must be processed at once without interruption.
In addition to 5-axis machining, Astell&Kern has perfected it's crafting of metal through thousands of hours of trial and error. Only after mastering these techniques that Astell&Kern has developed, can the beauty of the metal shine through.

The vibration-free processing machines used by Astell&Kern are the same ones used by expensive Swiss luxury watch manufacturers. This is reflected in the crafting of the volume wheel which is processed precisely like the crown of a luxury watch for the best operating feel.
Astell&Kern products are designed to achieve perfect integration at whatever angle you look at it in your hands.

The Aluminum body on the SR25 provides maximum sound quality, while suppressing noise as much as possible. The use of laser ground extension technology gives you the best sound possible, without interference or distortion.

Astell&Kern combines these small parts to make a big difference in the quality of our products that no other manufacturer can match.

Latest System Optimization for a Better User Experience

The SR25 firmware is based on Android 9.0, which adds a number of behind the scene features and upgrades to provide more stable operation over previous versions of Android OS. The use of Android 9.0 ensures the most popular music streaming apps installed via Open APP will be fully compatible with your Astell&Kern player now and with future app updates.

Astell&Kern customizes Android to provide a fully optimized system and user interface, designed to give users a smooth, fluid musical playback experience.

Our Take
If you need portability and simplicity above all else in an audiophile quality DAC, the DragonFly Cobalt is what you’re looking for. With the right mix of simplicity, extreme portability, and sound quality, the DragonFly Cobalt is a great tool to help you bring out the best in your music wherever you go. Read our full review here.

From AudioQuest
DragonFly Cobalt, our new flagship DAC, takes what music lovers around the world have come to expect from the multi-award-winning DragonFly family—naturally beautiful, seductive sound—and strips away fuzz and fog that weren't even noticeable until Cobalt removed them.

How is this possible? Like the critically acclaimed DragonFly Red, Cobalt has the robust 2.1-volt output to drive almost any headphone, uses a bit-perfect digital volume control for outstanding signal-to-noise ratio, enables seamless compatibility with Apple and Android devices, and is an exceptionally competent and affordable MQA Renderer.

AudioQuest, Gordon Rankin: A Beautiful Partnership
Like all previous DragonFly models, Cobalt uses Gordon Rankin's precedent-setting StreamLength® asynchronous-transfer USB code. Further, in Gordon's monoClock® technology, a single ultra-low-jitter clock generated from the ESS ES9038Q2M DAC chip runs the ESS chip functions as well as all microcontroller functions. This superior clock enables DragonFly Cobalt to provide greater resolution and clarity than DACs with multiple clocks.

Why the "Slow Roll...?"
Cobalt employs ESS's new flagship ES9038Q2M DAC chip. While the chips used in DragonFlys Black and Red are unbeatable for the price, the minimum-phase slow roll-off filter in the 9038 results in naturally expressive sound that is always emotionally engaging and never fatiguing—a beautiful combination of warmth and detail that we find equally exciting and soothing.

Killing the Noise
In Cobalt, we've taken what we've learned from our recent research and development in noise dissipation to employ power-supply filtering specifically designed to dramatically reduce the increasingly prevalent noise from WiFi, Bluetooth, and cellular signals. Successfully combating this noise is absolutely crucial to the preservation of the lowest-level musical details, particularly when it comes to high-res audio—and especially when applied to a portable-audio device such as DragonFly.

Bit-Perfect Volume Control and 2.1-Volt Output
Cobalt features the same ESS Sabre 9601 headphone amp and bit-perfect volume control that give DragonFly Red its unique combination of power and grip over the music. This solution ensures maximum fidelity, thrilling dynamic contrast, and excellent signal-to-noise ratio. The 2.1-volt output makes Cobalt and Red compatible with a wide range of headphones, including power-hungry, low-efficiency models.

The DC01 supports up to 32bit/384kHz PCM decoding and up to 256x Native DSD decoding, with a THD+N below 0.001% and providing high power output of up to 113mW @32ohm. With this you are more fully able to make full use of quality of your valuable music. Wonderful HiFi music starts from the heart of the music source.

The AK4493 is a desktop level stereo DAC chip, featuring AKM’s Velvet Sound technology. The signal-to-noise ratio has been improved when compared to the previous AK4490. It can be found in new generation desktop DACs and is widely used in high end portable audio players. With extensive work we have implemented the AK4493 into the compact DC01 DAC cable adapter.

True Balanced Headphone Amplifier

iBasso introduces the concept of balanced audio in professional audio, into this portable DAC cable adapter. It uses a true balanced circuit with dual ultra-low distortion LDOs to create a true balanced amplifier, which provides high output power with improved dynamics and resolution.

From Smartphone to Computer: UAC2.0 USB Soundcard

The DC01 uses a USB-C connector and utilizes the standard UAC2.0 USB receiver. It is compatible with most Android Smartphones and tablets on the market. It can also be connected to the Mac and Windows computers via the high-quality supplied C to A converter. This allows it to work as a USB Soundcard. With the DC01 using the standard UAC2.0 sound card chipset, Mac and Win10 computers are plug-and-play. For WinXP, Win7, and Win8 systems, please download the driver from iBasso's website. Once properly installed, it can be used as a USB soundcard.

DA01 Achieves 64-Step Hardware Volume with a Dedicated App

Windows 10 and Android 5.0 and above support the UAC2.0 protocol by default. However, for compatibility reasons, Android Smartphone manufacturers still use SRC on audio output. When DC01 is connected, the maximum volume is achieved by default, the software algorithm of the device is used to reduce the volume. The software algorithm can reduce the volume but cannot reduce the noise floor. Therefore, iBasso developed a UAC2.0 volume controller app to achieve 64-step hardware volume control, effectively reducing the noise floor while achieving a better audio performance.

Operating Instructions

The DC01 can be plug-and-play on Android Smartphones and tablets with Android 5.1 and above, without installing drivers or third-party apps (due to the Android device’s system or hardware limitation, there may be a low compatibility issue with some smartphones or tablets). On some Android devices, it may be necessary to manually turn on the OTG function in the system settings.

The DC01 uses a standard UAC 2.0 sound card chipset for plug-and-play on Mac and Win10 computers. For WinXP, Win7, and Win8 systems, please download the driver from the iBasso website. Once properly installed, it can be used as a USB sound card.

There is no built-in battery so the DC01 receives its power through the USB interface from the master device. The actual power consumption is related to the operation and the device system. Because DC01 has an audiophile DAC chip it is normal for the DC01 to get warm during use. *So far, we found that the DC01 has compatibility issues with the Samsung S9 and S10 smartphones. It works flawlessly with other Android smartphones. *The DC01 can be used without the UAC volume control app. With the iBasso app, you can use their 64-step hardware volume control.

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).
