Updated version of the SU-9, the SMSL SU-9 Pro takes the technical base of its predecessor while proceeding to an improvement of the integrated components in order to increase the performances. Thus, this new version embeds a new DAC ESS ES9039MPro, offering a sound restitution of a great richness and precision and allowing the support of high resolution audio streams up to PCM 32bit 768kHz and DSD512 as well as the decoding of MQA files.
The whole audio circuit shows a particular care in the selection of the components. There are no less than 11 OPA1612A, a USB XMOS XU316 interface, a CK-03 clock circuit for a significant reduction of jitter and a shielded and regulated power supply stage capable of providing a clean and stable electrical signal.
High quality Bluetooth reception
The SU-9 Pro, like its big brother, has a Bluetooth 5.0 receiver chip, allowing you to easily stream your music wirelessly from a smartphone or tablet, for example. In addition, it supports the aptX, aptX HD and LDAC transmission codecs for high-quality wireless sound reproduction.
