Cirrus Logic CS43198
Dual DAC Chip
Pair with Laptop via USB
A majority of people use a laptop as the primary source device to listen to music or watch movies. Since the laptop is an essential part of the audio chain there are headphones and devices designed to work a laptop or computer system flawlessly. With the availability of USB connectivity, it becomes easier to pair various devices like an Amp, DAC or even headphones without worrying about drivers or any additional piece of software.

Design
PEE51 is easily my favourite Dongle DAC. It gives you the Astell&Kern signature sound at a very affordable price, and you can pair these with IEMs that are upwards of Rs 1,00,000, and it's hard to believe how much detail and power you’re getting from a device this size.

DESCRIPTION
POWERHOUSE USB-C DOUBLE DAC FOR HIGH DEFINITION SONIC EXCELLENCE
Designed to complement Astell&Kern's series of Digital Audio Players, the PEE51 lets you enjoy the dynamic and lifelike high-definition sound on your computer and Android mobile phones without using a high-end sound card. The PEE51 features two Cirrus Logic CS43198 MasterHIFI DACs that support Hi-Res audio playback including native DSD256 and 32bit / 384kHz.
INDIGENOUSLY DEVELOPED AUDIO CIRCUIT FOR STABLE AND UNRIVALLED PERFORMANCE
Putting years of experience to best use, Astell&Kern has designed a highly intricate circuit on a small and 6-layered 14 x 41 mm printed circuit board (PCB). Even the micro resistors and tantalum capacitors used in the PEE51 are indigenously developed by Astell&Kern. These are capacitors that are used in the A&K DAPs, and they optimise audio circuits to reduce fluctuations leading to overall stability and unrivalled sound quality.
AN INDEPENDENT ANALOG AMPLIFIER TO ELIMINATE UNNECESSARY COLOURIZATION & DISTORTION
The power of CS43198 DACs is combined with an independent analogue amplifier to deliver highly authentic sound reproduction. This chip allows you to enjoy a dynamic and clear sound that is free of colourisation and distortion - just the way artists intend their music to sound. The PEE51 is compact and drives even high impedance headphones with an output level of 2 Vrms.
ENJOY ASTELL&KERN SOUND SIGNATURE ON YOUR ANDROID SMARTPHONES AND COMPUTERS
Offering the widely used USB-C connector, the Astell&Kern PEE51 is compatible with almost all the latest Android smartphones, tablets, Windows 10 computers and macOS. You can connect headphones to the PEE51 with a 3.5 mm connector. The PEE51 lets you discover the Astell&Kern sound signature using your audio devices. From full-size headsets to in-ears, you connect a host of headphones that support 3.5mm 3-pole and 4-pole plugs. Kindly note that 4-pole earbuds with inline controller and microphone functions are not supported.
ROBUST 4-CORE SILVER-PLATED COPPER CABLE FOR NOISE-FREE SOUND REPRODUCTION
Empowered with a custom 4-core cable for precise sound reproduction, the PEE51 improves disconnect resistance. With reinforced aramid fibre, the PEE51 can resist a tensile force of up to 200 Newton. This thick cable consists of spiralled silver-plated copper wires wrapped around a centre Technora Aramid core to eliminate external noise. This copper wire also helps to deliver clean and rich surround sound. There is unique shielding on these cables that eliminates distortion and noise in digital and analogue signals coming from the playback device.
"LIGHT AND SHADOW" THEMED ELEGANT DESIGN THAT BALANCES BEAUTY AND COMFORT
Featuring the "light and shadow" design, the USB-C DUAL DAC utilises a unique design that has been fundamental to Astell&Kern products. This design consists of a single centerline that crosses from right to left. The ratio of the angles is optimised to ensure that the sharp portions of the four top faces coincide at a single point. Reflection on each side of the design follows the movement of light. The surface is polished to make one-hand use more comfortable. Reflecting on the durability of other Astell&Kern machines, the PEE51 uses robust metal elements.
KINDLY READ THROUGH THE FOLLOWING PRECAUTIONARY MEASURES FOR BEST USER EXPERIENCE
Considering limitations of hardware, software and the overall system some of the devices might not be able to function perfectly with the Astell&Kern PEE51. iOS devices like iPhones and iPads are not compatible with the PEE51 currently while some Android devices may need changes in settings to work efficiently. If you are using the PEE51 with a computer, the computer will automatically install the required driver. However, a separate installation may be required for high-end audio playback. This extra installation file can be accessed from the Support-Download section of the Astell&Kern global website. Kindly note that to play hi-res audio files like DSD and PCM on your smartphones you will need a separate free / paid application that is compatible with high-definition audio playback.
It is advised to get the volume level checked before connecting headphones to the PEE51 as there are chances of some devices having maximum volume by default. When you are using the PEE51 with an Astell&Kern player as an external D / A converter the volume will be set to the highest, by default. Listening to music on high volumes can damage your listening. Astell&Kern does not recommend using the PEE51 with Astell&Kern players. Firmware updates may be available from time to time to enhance stability and performance. Visit the Support-Download section of the Astell&Kern global site to get more information on updates and to check if any update is available.
