Thickened heat sink with a silent long life fan enhances heat dissipation for power operation, reducing the risk of thermal throttling and improving reliability. current capability with low magnetic loss, small parasitic capacitance, and low heat generation; oxygen copper wire contributes to better sound quality; magnetic shielding provides strong anti electromagnetic interference performance. Extremely low noise and distortion, preserving a listening experience. Transparent sound with fast low frequency response, strong mid frequency texture, smooth frequency performance, and minimal signal loss for faithful reproduction. Use scenarios In power audio equipment such as hi fi amplifiers or dedicated headphone amplifiers where strong cooling and clean power are required. In professional recording studios or reference monitoring setups where low noise, low distortion, and EMI shielding are critical for accurate sound. In environments with potential electromagnetic interference or compact multimedia devices that require efficient heat management and reliable performance.
