The SMSL has been updated to version 2. For the latter, SMSL modified the design of the PCB as well as the USB firmware.
The SMSL A6 is a Class D integrated amplifier capable of delivering 2x50W and meeting all the requirements of compactness and contemporary design with high quality sound. The integrated Single Ended B&O ICE Power Series ASX low distortion amplification technology delivers surprisingly melodious and musical sound in a 45mm thick format.
With a high definition 32bit 384kHz asynchronous USB DSD 32bit, analog line and phono inputs, the SMSL A6 has the necessary connectivity to meet the vast majority of needs.
SMSL's intention with this A6 was to design a device with real high fidelity musical performances in a compact format. The bet is successful because of its design quality with high level electronic components. A MAX97220 AOP at the line input manages the analog part and a 32bit 768kHz AK4452 DAC decodes the entire digital / analog part. The A6 is therefore an amplifier that will fit perfectly into digital use but can still be combined with a turntable thanks to its high-performance analog phono input.
The USB and S/PDIF input is managed by the latest generation 32bit CM 6632A chip. This way, all your high definition files will be readable on this amplifier. From the simple DSD64 file to the elitist DSD512 and the DxD 32bit 384kHz PCM with very low jitter, the SMSL A6 is just as good at digital and analog reading.
Close to a digital source such as a computer and thanks to its headphone output on 3.5mm jack (up to 300 Ohm), the SMSL A6 will be the faithful companion of HiFi systems in the office or living room.
The DAC Out and Speaker output can be used at the same time.
