Hello, first of all, the real music fax m6i amplifier has many characteristics: the sound bottom is not thin, the thickness of the mid- and high-frequency is ideal, it can be well qualified for the playback of vocal software, and it can improve the timbre of music. It is fully expressed and has a slightly "hissing" noise, which has a good and unique musical expression effect. Then, if it is a fake music fax m6i power amplifier, the quality, service life, and subtle sound quality of the imitation, the sound quality and sound effects of the fake m6i power amplifier are far worse than the real m6i power amplifier. Finally, if the questioner wants to buy a real music fax m6i, there are currently fewer channels to purchase the music fax m6i, so you need to choose and buy carefully. I hope this can help you!
