Users who want to seriously enjoy music by using earphones rely on external earphone amplifiers with integrated digital/analogue converters such as the Oehlbach XXL DAC Ultra. The integrated converter from Burr Brown can convert signals up to 384 kHz and 32 bit. Data with lower resolution are respectively projected, to make full use of the technology. The carefully processed signal is available at two jack sockets and an analogue cinch output. The minimalistic design is combined with an intuitive handling: the input select switch and the volume control are enough for the perfect music enjoyment. An analogue input, two digital ports and USB offer all necessary connections. The good manufacturing of the compact earphone amplifier adds up to the positive overall impression.
