An amplifier
with no ifs, ands or buts

With decades of experience in developing compact, sound-strong all-in-one devices, the AS 2.3 was created based on the AVM X-STREAM Engine®. This high-performance model combines state-of-the-art technology with a minimalist, screw-free aluminum case, inspired by the flagship CS 8.3.

Comprehensive connectivity
for limitless streaming sessions

The AS 2.3 has all the modern connections: HDMI ARC for TVs, Bluetooth 5.0, USB A and digital and analogue inputs. Special highlights are the precise phono input stage for MM and MC as well as the newly integrated digital outputs with volume control.

Advanced
app control and future-proof streaming

The redesigned RC X App allows for intuitive control and easy management of large music collections. Thanks to the AVM X-STREAM Engine® high-resolution formats like DSD (256) are supported, and software updates ensure the system’s future viability in the long term.
