Esoteric is pleased to announce the launch of two new products: the Network DAC Preamplifier “N-05XE” and the Class A Stereo Power Amplifier “S-05XE“— Esoteric’s best-selling combo that has evolved into the new “XE” series. The product will be available for international shipment in Spring 2026.
Introducing the N-05XE
The N-05XE network DAC preamplifier features next-generation discrete DAC and network engine technologies for even higher sound quality.
Designed to deliver the highest sound quality in the smallest possible system configuration, the N-05XE features an optical network-compatible G4 network engine and a next-generation G2 discrete DAC. It also has a dual balanced preamplifier derived directly from the Grandioso models along with a high-quality built-in headphone amplifier. The “XE” model retains its acclaimed functionality while meticulously refining every circuit component through a newly optimized design. Enjoy the refined Esoteric signature sound to your heart’s content.
