What is MQA audio?

MQA is an award-winning British technology that delivers the sound of the original master recording. The master MQA file is fully authenticated and is small enough to stream or download.

Visit mqa.co.uk for more information.

The Attessa Streaming Amplifier includes MQA technology, which enables you to play back MQA audio files and streams, delivering the sound of the original master recording. All of the digital audio sources of the Streaming Amplifiers support MQA content, there are two types of MQA: ‘MQA’ or ‘MQA.’ MQA indicates that the product is decoding and playing an MQA stream or file, and denotes provenance to ensure that the sound is identical to that of the source material. ‘MQA.’ indicates it is playing an MQA Studio file, which has either been approved in the studio by the artist/producer or has been verified by the copyright owner.

‘OFS’ (Original Sample Rate) confirms that the product is receiving an MQA stream or file. This delivers the final unfold of the MQA file and displays the original sample rate.
