A modern all-in-one: CS 30.3
In the tradition and with our accumulated experience since the 1990s to develop compact all-in-one devices without compromise in terms of sound, the new high-performance All-in-One CS 30.3 has been created on the basis of the AVM X-Stream Engine® . Numerous new features have been incorporated into this 30.3 device and the new RCX APP also controls the CS 30.3 completely. Device towers and overflowing cable clutter become superfluous, all modern connections are available, so that even a TV can be connected via HDMI ARC. In order to achieve our goal of creating one of the most powerful sounding machines on the world market with this compact all-in-one, we have designed proven sound technologies into a shapely, screwless precision housing.
The main focus was on a completely modernized APP control system. The RC-X app clearly contains all important functions. The simplest, intuitively learnable operation as well as a clear and nicely designed user interface make the management of even large music collections child's play. This makes you want to explore new music on numerous streaming platforms. The AVM RC-X app is available for iOS (Apple) or Android-controlled devices. In addition, basic functions can also be controlled via the included RC3 Full Aluminium remote control.
The new AVM X-Stream Engine® can stream all high-resolution formats, including DSD (256). Our streaming engine is a complete in-house AVM development and is completely software-based, so it can be updated online in a future-proof manner. An HDMI (ARC) interface is also on board as well as the modern Bluetooth connection, further digital inputs and a USB A interface are standard. Special attention was paid to the high performance phono input stage for MM and MC. This high-precision input stage has been completely redesigned for the CS 30.3. This ensures even better sound, especially in combination with our rotation turntables. Completely new are the digital outputs, which can also be volume controlled. The HDMI ARC input makes it easy to connect TVs and control them conveniently.
The CS 30.3 has also made a big leap in terms of sound. This sonic advancement is based on the use of a 125W amplifier stage, which effortlessly drives even power-hungry speakers at all volumes. The new amplifier stages are based on the large CS 8.3 and have been optimized for use in the CS 30.3 housing.
The digital section in CS 30.3 was redesigned from the ground up in the course of the new development, because this crucial part of CS 30.3 is basically based on our decades of experience. A selected ESS from the new generation (9038 Q 2 M) is now used as a digital/analogue converter, which is also a clear gain in terms of sound, which benefits all digital sources and reproduces all high-resolution formats perfectly and true-to-life.
The CS 30.3 are available in the standard colours aluminium silver or black, for an extra charge also with the Cellini chrome front. Like all AVM30.3 devices, the CS 30.3 is manufactured entirely by hand at the factory in Malsch. You are welcome to watch our creative process in our 'making-of' video (QR code below). Repeated, intensive quality controls during all production steps and a break-in time of several days for each individual device secure our promise of maximum reliability in the long term and we grant a 2-year warranty on the compact CS 30.3, and an additional 2 years if registered online.
