NEW TOPPING NX7 NFCA Portable Headphone Amplifier High Performance Headphone Amp

? ¡¾NFCA Amplifier ¡¿The new NFCA amplifier circuit is specifically designed for portable amplifiers. The low idle power consumption allows for extended battery life. This is done while having 0.00007%THD+N and135dB SNR. The powerful thrust and quiet bottom noise can easily push the difficult big headphones and high-sensitivity IEMS. ¡¾Easily Drive The Full Size Headphone With High Performance¡¿ The NX7 can output 180mW of high power under a load of 300ohms, and with the help of 3 step gain setting, the small body can easily beat the full sized headphones. It is worth mentioning that even when the output is 200mw, the load distortion is only 0.00008%. ¡¾Equally Outstanding While Driving IEMS¡¿The low gain of NX7 is -13.8dB. When used with high-sensitivity-in-ear headphones, there will be almost no trouble of potentiometer bias in the comfortable volume range. ¡¾NX7 Has 20h Battery Life¡¿Due to the optimization for portable devices, the NX7 can get 20h of battery life at low and medium gains; even if it is witched to high gain, it can also get 10h of battery life. ¡¾Background Noise As Quiet As The Deep Ocean ¡¿The background noise of NX7 is only < 0.3uV, 50mV SNR is 104dB. The output impedance of NX7 is as low as 0.1¦¸. Even if it is driving high-sensitivity IEMS, it will not introduce sound coloration . You no longer need to worry about sound matching. ?
