The HD6 Powered Bluetooth Speaker is a perfect example of the extension of this mission. With music streaming services and digital music players becoming the centre of the modern music system, consumers have had to accept a loss of the premium components resulting in the loss of sound quality. The HD6 Series of Bookshelf Speakers are a culmination of 13 years of product development, combining the same exceptional sound quality with modern features, including high resolution aptX HD Bluetooth with 30 meter range. The built in analog amplifier allows traditional Hi-Fi speaker separation and the analogue audio inputs allow connectivity from any other analog source, including a turntable. The added S/PDIF Optical allows a digital source such as a TV to be connected.
