Pure Class A 100W per channel at 8Ω delivers zero crossover distortion. 118dB ultra low noise SNR paired with 800 high damping factor for ultra detailed, tight and natural audio performance. Built with premium all-metal chassis and professional-grade components for audiophile-level listening experience.
Engineered with the same core line architecture of the legendary Accuphase A-70, the MUSMYS A-70 brings flagship high-fidelity sound quality to audiophiles at a far more accessible price point. With a specially designed pre-stage separate amplification circuit and optimized internal gain ratio, this pure class A amp achieves an ultra-high 118dB signal-to-noise ratio, producing nearly silent background and stunning detail retrieval that lets you catch every subtle nuance of your music, from soft breath in vocal tracks to faint overtones in acoustic instruments. The 800 damping factor at 8Ω 50Hz provides extremely tight control over your speakers, delivering deep, solid low end without any muddiness or delay even at maximum dynamic output. It features exceptional transparency and clarity, with crisp, well-defined instrument contours and rich natural harmonics that never sound harsh. The mid and high frequencies extend smoothly, rendering the tone of violins, pianos and human vocals with exceptional lushness and naturalness, with precise soundstage positioning that recreates the original live performance atmosphere perfectly. Crafted for US audiophiles who pursue uncompromising sound quality, this heavy-duty 47KG all-metal amplifier is equipped with oversized heat sinks, dual high-power toroidal transformers, high-capacity filter capacitor array and gold-plated speaker terminals, all to ensure rock-solid stability even during long hours of high-load operation, making it the ideal upgrade for your reference-level home audio system.
