The 891 unites a network player, DAC, and reference-grade analog preamplifier within a single chassis, granting precise mastery over the entire audio chain from digital source to power stage. Its M-VOL3 analog volume control delivers absolute precision and silence, even at the lowest listening levels, while each stage is independently powered in an optimized dual-mono layout. The MDE2 digital engine handles PCM up to 384 kHz and DSD up to 22.6 MHz via USB, and the MiND 2 platform supports Roon Ready, AirPlay, Spotify Connect, and TIDAL Connect. All modules are physically and electrically isolated for maximum clarity and stability, yielding a fluid, balanced, and faithful playback experience across all formats and sources.
