Know before you buy
The MQ-88uC delivers an organically toned, three-dimensional sound. By utilizing a triode configuration with KT88 tubes, it prioritizes musical purity, warmth, and exceptional detail retrieval.
The MQ-88uC is highly versatile and features dedicated output taps for 4Ω, 8Ω, and 16Ω speakers. This allows it to pair effectively with a wide range of high-fidelity speaker systems.
This unit provides 25 watts per channel. While this may seem modest compared to solid-state amplifiers, the tube-driven output is designed for high-quality, nuanced listening rather than sheer volume.
Yes, the MQ-88uC is a dedicated power amplifier. You will need to connect it to a separate preamplifier or a source component with its own volume control to manage your audio system.
Like all tube amplifiers, the MQ-88uC requires periodic tube replacement as they age. The unit uses a total of eight tubes—four KT88s, two ECC83S, and two ECC82s—which are accessible for maintenance when necessary.
Beyond its aesthetic appeal, the build quality includes proprietary Luxman-developed transformers and premium components. These elements are engineered to minimize noise, ensuring a quiet, 'black' background that allows subtle musical details to emerge clearly.
