AVM Inspiration CS 2.3 as a compact streaming CD receiver

The AVM Inspiration CS 2.3 is a streaming amplifier for modern audio systems. As the high-performance version of the Inspiration All-in-One, the model combines streaming functions, CD playback, digital and analog connections, and an integrated amplifier section in a compact enclosure. This makes the CS 2.3 suitable as a central hub for various music sources and for setups with bookshelf or medium-sized floorstanding speakers.


Streaming, app control and versatile connection options

The foundation of the AVM Inspiration CS 2.3 is the AVM X-STREAM Engine®. It supports high-resolution formats up to DSD256 as well as PCM with 32-bit / 384 kHz and is designed for future requirements via software-based updates. A key feature is the RC X app, which enables modern and user-friendly control.

The equipment includes HDMI (ARC), Bluetooth 5.0, several digital inputs, and a USB-A interface. In addition, there is a powerful phono input stage for MM and MC systems. The volume-controllable digital outputs are also noteworthy, as they expand the device's range of functions compared to classic compact solutions.


Sound, amplifier technology and digital signal processing

The amplifier technology of the AVM Inspiration CS 2.3 is inspired by the Ovation CS 8.3 and delivers 140 watts at 4 ohms. High-resolution audio formats are processed via the ESS DAC 9038 Q2M in the revised digital section.

Phono, CD, and digital sources integrate sensibly in one device. This allows the AVM Inspiration CS 2.3 to cover both classic HiFi applications with CD and turntable as well as modern streaming and TV connections via HDMI ARC.


Design and manufacturing

The AVM Inspiration CS 2.3 also makes a clear statement in terms of workmanship. Each device is handcrafted in Malsch. Enclosure components from local suppliers underline the standards for build quality and finish.
