Description
Successor to a class leader
Introducing A&norma SR35 – Successor to the multi-award-winning SR25 MKII, the premium hi-resolution audio device is the first to feature the brand’s own New Generation Amp technology and an interchangeable Quad DAC Mode as well as a brand-new user interface.

Exclusive circuitry that pushes sonic boundaries
Boasting 20 hours of continuous playtime, the SR35 deploys the first Dual/Quad DAC switching mode in the A&norma series, enabling users to easily adjust the sound and power output while improving power efficiency. The brand’s patented TERATON APLHA technology ensures balanced dynamics and class-leading resolution throughout listening sessions.

Pocket powerhouse
Elevating the series to new heights of audio excellence, the new SR35 is the first in the A&norma series to be equipped with New Generation AMP technology from Astell&Kern. Featured in the latest high-end A&ultima and A&futura range, the exclusive, in-house amplifier effectively eliminates noise at a high-power output to ensure SR35 listeners experience the clearest possible, distortion-free sound at all times. The new amplifier technology built into the SR35 also boasts a two-step gain mode for the ultimate Hi-Fi experience. New gain settings generate a high current output to produce a consistently powerful sound with excellent driver control to ensure seamless use of sensitive IEMs and hard-to-drive headphones.

An interface fitting for listening excellence
Listening excellence For the most seamless of listening experiences, the SR35 comes with a reimagined, crimson-themed, intuitive user interface featuring a new album artwork search function to allow audio connoisseurs to rediscover the joy of the art form.

Ultimate connectivity through Wi-Fi and Bluetooth
Equipped with Dual Band Wi-Fi (2.4/5GHz) to provide strengthened network performance, music in the highest possible quality can be enjoyed through a wide range of streaming and Roon Ready services. The SR35 also brings your other devices up to its level. Music from an external device, such as a smartphone, can now be played back in high quality on the SR35 through a new BT Sink function.

Roon Ready and MQA Support for Hi-Fi Fans
Further new functionality comes with Roon Ready status, plus full MQA 8x decoder support – enabling the SR35 to natively play and stream Hi-Fi MQA tracks. Both additions keep the new model true to the A&norma concept of playing authentic sounds anywhere and at any time.
