Stereophile’s Recommended Components 2025 list is out, and MOON by Simaudio has earned top honors!
MOON 891 – Grade: A+ (Digital Processors) & A (Preamplifiers)
Praised for its state-of-the-art performance, exceptional phono stage, and musicality to the core, the 891 was described as a “fine-sounding, easy-to-operate one-stop front-end” that delivers “truthful full-range sound.”
MOON 861 – Grade: A (Solid-State Power Amplifiers)
This powerful dual-mono amplifier impressed with its neutrality, soundstaging, and dynamics, offering some of the best measured performance ever encountered by Stereophile.
The MOON 861 is a power amplifier with the pedigree of the distinguished MOON 888 and the wholistic design philosophy of the North Collection.
