Taking it to the next level the 8300CDQ now includes MQA technology, which enables you to play back MQA audio files and streams, delivering the sound of the original master recording. MQA (Master Quality Authenticated) 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.
Digital Filter Optimisation
As digital audio reproduction technology has progressed, the importance of the characteristics of reconstruction digital filters has become more appreciated. The Audiolab 8300CD features user-selectable digital filters for optimal listening. These filter settings allow the user to tune the 8300CD’s performance to suit his or her preference, depending on system configuration and musical taste. These filters are available for CD and PCM audio via digital inputs.
• Optimal Spectrum
• Optimal Transient
• Optimal Transient XD
• Optimal Transient DD
• Sharp Roll Off
• Slow Roll Off
• Minimum Phase
the 8300CD also adds four DSD filters that progressively attenuate the out of audio bandwidth noise floor. Given stable, wide-bandwidth amplification and loudspeakers that can handle high power ultrasonic output, the user can choose the widest bandwidth setting of 70K. More modest equipment will benefit from the lower bandwidth settings, as may files that contain little or no recorded ultrasonic musical detail.
The four DSD settings are:
• Normal (47K)
The new 8300CD can accept and process data up to 32-bit/384kHz; this is a far higher specification than that required even by current hi-res music formats, ensuring the 8300CD is fully equipped for future advances in ultra-high-definition digital sound.
The USB input now also accepts DSD data, as well as PCM. This is a significant addition, as DSD has an important role to play in the developing high-res digital download scene. Accordingly, the filter section now includes four extra filters for DSD playback, allowing the user to optimise the noise floor to suit the performance of the source file and the bandwidth of associated equipment such as amplifiers and loudspeakers.
The uprated digital processing associated with the increased resolution at the USB input delivers additional sonic benefits, for both CD replay and other connected digital sources, whatever the resolution of the file. In advancing the capability of the USB input to include files of up to 32-bit/384kHz, the processing of data preceding and within the Sabre DAC has increased the subjective resolution of musical detail and dynamics, resulting in a more energetic and transparent performance that sets a new standard for CD players at this price level.
