First Look: Grace Digital Bluetooth Digital Amplifier

Grace Digital now offers two compact digital desktop amplifiers with Bluetooth, an aux input, plus bass, treble and balance controls. It ditches cheap plastic components for a more premium approach which includes a metal chassis, solid control buttons and gold-plated binding posts. All that's missing is a subwoofer output. Still, these affordable amps show a lot of promise. In our video we take a close look and offer our first impressions.
