KGUSS Topping A50 III NFCA Headphone amp Pre-Amplifier - SE/BAL Input 6.35mm Single-end 4.4mm Balanced Jack 3500mW x2 Powerful Output (A50III Silver)($199.00Value)

Description

👍 Ultra-high Performance NFCA modules ▶️ A50 III uses the same NFCA module from A50s. Voltage Current hybrid feedback architecture along with UHGF technology provides excellent DC and AC performance. High output current drive capability allows the amp driving low impedance headphones with ease. 👍 Full aluminum case ▶️ A50 III has a unique integrated design. It has gone through dozens of processes of planning, design and precision machining from solid aluminum bricks. CNC machining provides excellent electromagnetic shielding while giving the A50 III a smooth appearance and superior strength. It is not only the masterpiece of craftsmanship, but also the perfect combination of art and technology. 👍 Single-end / Balanced application ▶️ The A50 III has 6.35mm single-ended and 4.4mm balanced headphone jack, as well as RCA single-ended and TRS balanced input. It is simple and efficient for you to choose different input and output combinations. 👍 Wide range of adaptation to headphones ▶️ The A50 III has three gain selections for all types of headphones. With low noise of 0.3uVrms, IEMs will not be disturbed by any noise floor. 👍 Powerful Output ▶️ With a powerful output of 3500mW x 2, the A50 III ensures that most headphones can maximize their performance. It maintains a low distortion rate of less than 0.1% even at high power.
