Circuit structure used a ultra-Class A (Class AA) circuit, because voltage amplifier stage of Class AA headphone amplifier is equivalent to a no-load state, no matter how the load followed by the headset, it will not affect the voltage amplifier stage of work, which is common Amplifiers can not achieve that status. As results, it will make a very real interpretation of the music, space and very good positioning performance, and efforts to extend the sense of sound performance; it is just a little weird. In addition, we use HIFI grade components and process to make it, and bring a better listening experience.\u003c\/span\u003e\u003c\/p\u003e\n\u003cp style=\"text-align: center;\"\u003e\u003cspan\u003e\u003cimg src=\"\/\/cdn.shopify.com\/s\/files\/1\/1105\/6138\/files\/WETA-BAA200_1l.jpg?v=1497318881\" alt=\"IWISTAO HIFI Headphone Amplifier Portable Ultra-Class A (Class AA) OPA2604 plus LM4562 320Mw 16~300ohms Li Battery Ultra-thin Body\"\u003e\u003c\/span\u003e\u003c\/p\u003e\n\u003cp\u003e\u003cspan\u003eSelection aspect of the op amp, we used OP IC OPA2604 plus LM4562 match, we passed several tests comparing those match, we find that they can complement each other; If the preamp use OPA2604, and power stage use LM4562, we tested them with a 20KHz square wave, which output waveform distortion is very small.
