Specifications and features

Overview

The Omnia A300SE uses a compact yet powerful Class D amplifier capable of signal bandwidth up to 100 kHz with an advanced integrated feedback design and error correction for very low noise and distortion.

Marcel

I am very pleasantly surprised by this product. A compact, high-quality piece of equipment, a Class B amp/DAC/streamer that enhances my speakers.

Je suis très heureusement surpris par ce produit. Un équipement compact de très bonne qualité, un ampli/dac/streamer de classe B qui bonifient mes enceintes.

Powerful amplifier that fills my Triangle speakers well.
I'm deducting one star for the poor quality of the Omnia app on Android, which I find difficult to use with my large music library located on my NAS (or on my PC). The app can only read about 30 tracks out of more than 5000. Bose does infinitely better, but connecting my Soundtouch box to the amp can only be done, for lack of suitable connectors, through a DAC and then an optical link. This reduces the quality from 192 kHz to 48 kHz...

Ampli puissant qui remplit bien mes enceintes Triangle.
Je retire une étoile pour la piètre qualité de l'application Omnia sur Android qu'il m'est difficile d'utiliser avec mon importante bibliothèque musicale située sur mon NAS (ou sur mon PC). L'application ne sait lire qu’à peu près 30 titres sur plus de 5000. Bose fait infiniment mieux mais la connexion de mon boîtier Soundtouch avec l'ampli ne peut se faire, faute de connecteurs ad hoc, qu'à travers un DAC puis liaison optique. On passe alors de 192 Khz à 48Khz…
