About the C-700u
The Luxman C-700u, released in 2015, is a versatile solid-state line-stage control amplifier featuring a discrete unbalanced preamp circuit with Luxman's proprietary ODNF version 4.0 for minimized distortion and high-frequency noise. It employs the precision LECUA 1000 88-step attenuator for accurate volume control, tone controls (bass and treble), loudness function, and line straight bypass. Designed with a loopless chassis and gradient cast-iron legs for vibration isolation, it offers balanced XLR and unbalanced RCA inputs/outputs, including recording loop and monitor functions. Reviews praise its refined, natural sound with excellent clarity, dynamics, and build quality, often paired with the M-700u power amplifier. Production spanned 2014-2020; currently available refurbished.
