Cabasse Abyss: presentation


The Cabasse Abyss connected amp replaces the Cabasse Stream Amp 100 from 2015, but completely updates it with the manufacturer’s latest innovations and research, as well with a modernized design. Combining luxury and minimalism, this amp features an entirely metallic chassis with fairly compact dimensions (24.5 x 9.7 x 22cm). The sides are entirely occupied by large heat sinks with solid aluminum fins. The center of the curved front panel features a circular touchscreen that is identical to that of the prestigious Cabasse Rialto speakers.

The Cabasse Abyss amp has a luxurious and elegant design with a circular touchscreen on the front panel.

Reminiscent of a porthole, the screen of the Cabasse Abyss is very practical. It allows you to quickly select the source, change tracks, access your favorites and view the cover art of the music being played. Its brightness can be adjusted to ensure optimal legibility, even in a sunny room. You can set a timer to put the screen in standby mode, or to leave it on while the amp is running.

There are many features that can be quickly accessed via the Cabasse Abyss’s touchscreen, including track switching, favorites and source selection.

The touchscreen is surrounded by a rotating ring that allows you to set the volume. The movement is smooth, ensuring a precise and intuitive adjustment. However, there is one inconvenience: dust inevitably accumulates around and underneath it. After two months with this amplifier, we could hear the dust when turning the ring. Although the particles are easily dislodged, this stands in contrast to the refined and luxurious look that this amplifier aspires to embody.

DSP-enhanced amplification

The Cabasse Abyss amplifier is equipped with a class D amplification section that can deliver an impressive 2 x 120W into 8 ohms or 215W into 4 ohms. Thanks to exclusive DFE (Dynamic Fidelity Enhancer) technology, the dynamics of this Cabasse amp are optimized depending on the listening volume. This technology takes into account the volume, the reproduced frequencies and the track to ensure a balanced and dynamic sound, even at low volume. A technique that has already shown its strengths on Cabasse’s connected speakers, including the Cabasse The Pearl Keshi 2.1 system.

Thanks to the combination of its high output power of 2 x 120W into 8 ohms and DFE technology, the Cabasse Abyss amp ensures dynamic and consistently balanced sound.

Thanks to its high power, the Cabasse Abyss amplifier is able to efficiently power the majority of Cabasse bookshelf and floorstanding speakers, but also speakers from other brands. Naturally, it blends harmoniously with the speakers of the French manufacturer from which it extracts the best performance thanks to specific algorithms for each model, including the Cabasse Minorca MC 40, Cabasse Murano, Cabasse Murano Alto and Cabasse Java MC40. Called DEAP (Digital Enhancement of Acoustical Performances), these algorithms take into account the performance of each speaker to offer musicality and settings adapted to the associated models. More than 290 million operations are performed every second to adjust the dynamics, power handling, balance and naturalness of the listening experience.

The Cabasse Abyss connected amplifier features many algorithms calibrated to optimize the sound of the latest Cabasse speakers.

The Cabasse Abyss connected amp can also fine-tune the music reproduction according to the listening conditions. This acoustic calibration system works without a microphone. In the app, you simply have to enter the placement of the speaker based on three presets: in a corner, on the TV cabinet or next to the sofa. It is also possible to select the listening position: a sofa very close to the speakers, in the center of the room or next to a wall. The latter feature mainly influences the bass level to avoid creating resonance in the room. Last but not least, a two-band equalizer lets you adjust the bass and treble levels.

In addition to the DSPs adapted to each Cabasse speaker model, the Cabasse Abyss amplifier allows you to customize the sound reproduction and adjust the performance according to the configuration of the listening room.


The Cabasse Abyss connected amp provides the same network features as the speakers in the Cabasse The Pearl range. Once connected via WiFi or Ethernet, it can play music shared through DLNA from a NAS or computer. The internal DAC then handles the majority of AV, MP3, AAC, WMA, AIFF, FLAC, ALAC and Ogg audio formats, as well as DSD files up to DSD128.

The Cabasse Abyss connected amp can access many online music services, such as Deezer, Napster, Qobuz, Spotify and Tidal.

Deezer, Napster, Qobuz, Spotify and Tidal are also supported in the Cabasse app, which is free to download for iOS and Android. This app provides access to thousands of web radios via vTuner. It is also possible to stream music from a mobile device, a tablet or a computer using AirPlay 2 or Bluetooth (SBC and AAC codecs).


In addition to its many streaming options, the Cabasse Abyss amplifier has a wide range of connectors, with two RCA inputs and an optical input to connect a preamplified turntable or a CD player, for example. A handy HDMI eARC port is also included to connect a TV. Lastly, the amp features a subwoofer output.

Thanks to its analog and digital inputs, the Cabasse Abyss amp can be easily connected to the majority of audio and video sources, including a TV via HDMI eARC.

All the connectors are located on the rear panel of the amplifier. There is an LED that is constantly lit when the system is switched on. It’s quite bright and can be annoying when the Cabasse Abyss is installed in a bedroom or near the TV. It would have been nice to be able to deactivate this indicator light from the mobile app. This could easily be corrected by a future update.

Very well designed, the Cabasse app ensures smooth navigation and allows quick access to the various streaming services, to the music shared over the network, as well as to numerous settings.

For this review, we connected the Cabasse Abyss to the Cabasse Minorca MC 40 bookshelf speakers, then to the Cabasse MC40 Majorca floorstanding speakers as well as the Cabasse Egea 500 and Cabasse Galion VII vintage models. We mainly used the amp’s integrated network player as the source, as well as Teac CD transport connected via optical.

The Cabasse Abyss amp proved to be very balanced and natural with the Cabasse Minorca MC 40 bookshelf speakers thanks to the algorithm specifically calibrated for these models.

Cabasse Abyss: listening impressions

The Cabasse Abyss amplifier displayed great clarity when reproducing music with transparency and a sense of detail. From the very first tracks we listened to, we noticed the Cabasse sound signature, with a well defined soundstage and pleasing tonal balance. The bass was deep and dynamic without being overpowering, the mids were perfectly articulated, and the highs were punchy without being aggressive.
