Nobsound NS-02G PRO HiFi Single-Ended Class A Stereo Amplifier

Features Warm and Natural Sound: Built on a single-ended Class A topology, the NS-02G PRO delivers low-distortion output with natural warmth and realism in vocals and instruments. Its smooth, immersive soundstage is perfect for long listening sessions in cozy setups or dedicated HiFi spaces. Fully Symmetrical Circuit: The fully symmetrical amplifier circuit reduces phase distortion and maintains signal integrity throughout the frequency range. This ensures cleaner output, improved imaging, and greater musical nuance, especially in acoustic and vocal-rich recordings. Powerful Enough for Most Speakers: With RMS output up to 30Wx2 (8Ω) / 42Wx2 (4Ω) in Class A operation, it can effortlessly drive most bookshelf and floor-standing speakers. Enjoy full-bodied sound with punchy bass and detailed mids, whether you're spinning vinyl, streaming, or playing CDs. Audiophile Components: With Toshiba 2SA1943/5200 transistors, 150W copper toroidal transformer, ALPS potentiometer, and 40,000μF capacitors, it ensures stable current, deeper bass, and wider soundstage. Gold-plated RCA jacks preserve purity and pluggable op-amps allow higher playability. Flexible Inputs and Safety Protection: Dual RCA inputs with an input switch support quick source switching and comparing without plugging and unplugging cables. Built-in protection systems like DC protection, surge-protected delay, and overheat protection, keep both your amp and speakers safe. Q: How can I replace the op-amps? A: The swappable NE5532 op-amps are located beneath a relay module. You’ll need to remove a few screws to access and replace them. Please proceed carefully or contact us if unsure.
