April Music EXIMUS DP1 High End Digital to Analog Converter

The EXIMUS DP1 is a high-end digital to analog converter up to 192kHz/24Bit, which can also be used as a pure preamplifier and top-quality headphone amplifier.

The DP1 has 6 digital inputs including USB 2.0. Each input supports playback of files up to 192kHz/24Bit (44.1, 48, 88.2, 96, 176.4, 192kHz). For USB this is accomplished with the ultimate USB 2.0 solution from XMOS with its super-quality oscillators (2 separate oscillators for the multiples of 44.1 and 48kHz).

Alex Rasmussen of A-Rex/Neal Feay designed the chassis cosmetics. Alex owns a full-capacity machine shop in Santa Barbara, CA and is famous for his remarkable industrial designs for Ayre, Constellation Audio, Resolution Audio and many others. The basic design concept of the chassis is the leaf. It represents springtime and with it the month of April like our company name. The volume control, engraved details on the top and all the lines are based on this leaf theme.
