What HFL Thinks
A&norma SR35 – At HiFi Lounge we are really excited to offer the Astell & Kern portable players to our customers. It was only when I went on holiday recently and took my iPod that I realised actually how poor the sound quality was and that I now have a large 24-bit library that I couldn’t play so that led me to the Astell&Kern players. These really are a revolution in portable music, not only do they look and sound stunning they are also able to drive high end headphones, plus stream wirelessly from your computer or NAS. These players really do offer high end audio in your pocket like has never been heard before.
Hi-Fi Sound on-the-go
The A&norma series was created to enjoy the premium sounds of Astell&Kern in a portable size with best in class specifications.
SR25 MKII, the previous model in the series, was loved by audio enthusiasts and those just starting their personal audio journey thanks to its portable size and powerful Hi-Fi sound through a 4.4-mm balanced jack.
The A&norma SR35 inherits these strengths while applying the amplifier and audio design that was applied to Astell&Kern’s premium products to deliver the authentic sound quality that Astell&Kern are so well known for. The ultra compact SR35 features 20 hours of continuous playback, while supporting Quad DAC and two-step Gain control, and the A&norma line’s first introduction of New Generation Amp technology with Astell&Kern’s long-standing know-how for an even more delicate and clear Hi-Fi sound at higher output.
We have also applied our new UI/UX with improved visuals and usability to the SR35 for a more immersive music experience. In addition to this the SR35 is equipped with Roon Ready and MQA full decoder support to further enhance the performance of our A&norma line.
DESIGN
The SR35 visualizes the powerful portability of the A&norma series into its design.
The intense dynamics of the A&norma series are symbolized as a mighty warrior’s sword and shield on the device. The single bold line on the side and the surface that gets bigger at the bottom represent a sword of battle, and the delicately refined volume control and its concave surface symbolize a shield. These symbolic shapes found in the SR35’s design represent a warrior’s powerful force and characteristic.
An “A” pattern on the rear glass creates a sophisticated rectangular pattern. This unique pattern on the SR35 symbolizes the first use of Quad DAC architecture in the A&norma series.
We kept our iconic angular display which works perfectly in the hand, further redefining the characteristic of the series.
