The 838 is able to offer this warm, accurate analogue hifi sound through the use of its Pure Direct Analogue Path. This is an optional sound mode that shuts down all digital circuitry when listening to vinyl records or other high-quality audio sources. The sound signals are routed via the phono or analogue inputs to the amplifiers, allowing for a clear and uncompromising sound, completely free from digital noise or distortion. 

Digital audio lovers are catered for though, as the high quality DAC chipsets within the 838 allow for 5.6mHz DHS or 192/24 high resolution streaming. This can be done via the free-to-download smartphone app. High quality Bluetooth connection is also present within the 838 for a no-hassle streaming solution.
