Astell&Kern SA700 Portable Music Player

Past Meets Present, SA700

With the launch of Astell&Kern's first product in 2012, we always aim to deliver uncompromising sound to music lovers.

One day we decided to ask ourselves a question - "What if we combined Astell&Kern's first starting point and present?"
- We wanted to combine the analog sensibilities that remained in our hearts with the sound technology
that has evolved over the years since our first product was released.
We wanted to create the best sound that only we can do.

"Past Meets Present" The SA700 is a product where past emotions and current technology meet.
The SA700 is an evolution of technology and design that deliver the ultimate sound to Astell&Kern original design and sensibility.

Emotional Retro Design
Intuitive LED Indicator
New Special GUI
Stainless Steel Body for Premium Sound
Ideal Size for Portability
Dual DAC of AK4492ECB from AKM
32bit / 384kHz, Native DSD256 support

We took the original design of AK120 and redesigned it into a simple, but refined form.
With the latest technology, the deeper and stronger sound of the SA700 delivers new experiences and values not found in other products.

First DAP Using AKM AK4492ECB DAC

The SA700 is the first DAP to use a AK4492ECB Dual DAC to give a new sound signature.

AKM's AK4492ECB is a DAC that aims to achieve the best performance in the industry by utilizing the technology obtained by developing AK4497EQ.
It has a lower power consumption and similar audio performance compared to AK4497EQ, making it the best DAC for a portable DAP.

Only Astell&Kern's Sound Technology know-how has made the DAC's performance even more perfect.
Now you can enjoy premium sound close to the original performance with the SA700 and the AK4492ECB.

Unchanging Value, Stainless Steel

The SA700 uses stainless steel, which is corrosion-resistant and durable, for maximum material strength and beauty.

Since it takes a lot of time, skill and cost to process the material, it is often only used for expensive products. The SA700 uses stainless steel because it provides the perfect sound.

Stainless Steel delivers both luxury and balanced, clean sound
Feel it at the SA700.

Deliver the perfect original sound

SA700 offers the optimal condition to deliver perfect original sound.
SA700 is capable of bit-to-bit playback up to 32bit 384kHz and native DSD playback up to 11.2MHz,
delivering detailed, distortion-free sound just as the artist intended.

Intuitive LED Indicator

The LEDs around the volume wheel are not just visual effects, but provide the listener information
including volume and status of the currently playing song.

Different colors are displayed depending on the bit depth of the song being played,
and 150 levels of red saturation are displayed to reflect the current player volume.

* LED can be turned on or off according to user setting.

New GUI where the past and the present coexist

SA700 maintains the convenience of Astell&Kern's UI combined with a new GUI that reminds users of our 1^st generation players.

You can combine Astell&Kern's past and present through the GUI which is reinterpreted by using Astell&Kern's various color identities.
