Compact power:
The new CS 30.3
CD receiver including streaming

The CS 30.3 CD receiver combines AVM’s decades of expertise in high-performance all-in-one devices with cutting-edge technology. Built on the AVM X-STREAM Engine®, it offers simple operation through the new RC X App and versatile connectivity, including HDMI ARC for TV integration, replacing complex device stacks and cable clutter.

Modernized control with the RC X App

The AVM RC X App offers a completely modernized control with an intuitive and elegant user interface. It allows for easy management of large music collections and promotes the discovery of new music on platforms such as TIDAL, Qobuz or HighResAudio. The app is available for iOS and Android, while basic functions can also be controlled via the included RC 3 full-aluminium remote control.

High-performance
in compact design

Based on the AVM X-STREAM Engine® , the CD-receiver CS 30.3 combines decades of experience in all-in-one device development with the latest technology. The new RC X App fully controls the device, and thanks to modern connections, including HDMI ARC, towers of devices and messy cables are a thing of the past. AVM has miniaturized proven sound technologies from the flagship CS 8.3 and integrated them into an elegant, screw-less housing to create one of the most sound-strong compact receivers worldwide.

AVMs
X-STREAM Engine®

The AVM X-STREAM Engine® streams all high-resolution formats, including DSD (up to DSD256), and is future-proof with online updates. It features HDMI ARC, Bluetooth 5.0, digital inputs, and a USB-A interface. Highlights include the new phono input stage for MM/MC and volume-controlled digital outputs. The HDMI ARC input also enables seamless TV connection and control.

The digital section of the CS 30.3 has been completely redesigned, drawing on AVM’s decades of expertise. A selected next-generation ESS converter (9038 Q2M) ensures superior sound quality and enables perfect, true-to-life reproduction of high-resolution formats. This advanced converter significantly enhances the playback of all digital audio sources.
