AUNE Aune X7s Pro Class-A headphone amplifier Silver

Aune X7s Pro Class-A Headphone Amplifier with Balanced Output The X7s Pro is a headphone amplifier with a Class-A design and features both single-ended and balanced outputs. Thanks to its high sound quality, powerful output, and broad compatibility with most headphones and earbuds, this is a high-quality amplifier for demanding listeners. Heritage of a Classic A new masterpiece from the successful designers behind the Panda and B1 headphone amplifiers. Get the Most Out of Your Headphones With three adjustable gain levels, the X7s Pro is suitable for almost all types of headphones and earbuds. There is always a setting that perfectly matches your setup. Compact Size Only slightly larger than a CD, the X7s Pro can easily be placed in various listening environments. It can also function as a pre-amplifier. In combination with the X7s 2021, you can effortlessly build a desktop HiFi system. Powerful Performance With eight BJT transistors, independent amplifier circuits, and a positive and negative power supply, the X7s Pro is designed to get the most out of your headphones. Single-Ended & Balanced The X7s Pro features both a 6.35 mm single-ended output and a balanced XLR output, allowing you to choose between two different listening characteristics. Experience the Beauty of Class-A The special Class-A amplification adds extra warmth and richness to the sound. You will feel the music and be moved by it. Class-A, also known as A-class, means that the output stages conduct continuously, regardless of whether there is an input signal. This keeps the current constant and minimizes distortion. Due to its very low open-circuit distortion, it is considered one of the most ideal amplification methods for audio. Class-A amplification is known for its full and clear sound. Components operate continuously within their linear range, virtually eliminating distortion. This results in a highly detailed, rich, and natural sound, especially with subtle signals. Excellent Specifications After four optimizations of the printed circuit board (PCB), the frequency response (20Hz–80kHz) achieves an accuracy of ±0.3 dB and a THD+N of only 0.0002%. This results in a wide soundstage, a quiet background, and an abundance of detail.
