300B Introduction:
1: The sound of 300B is quite distinctive. The playback of vocal, violin and light music is quite sweet. At the same time, the sound background has a certain thickness. The high frequency is transparent and delicate, the low frequency is not too exaggerated, and the strength is fair. The 300B has a unique sound field, which some people say is rich in overtones. This pair of power amplifiers sounds like they have a little reverberation. The sound field is large, and the stereo sense is good.
2: As for the thrust, the tri frequency connection is natural, the voice is loose, and the 300B tone dye is large. Everything is sweet, but it is very pleasing to the ear. High frequency is very good in detail, medium frequency is outstanding, low frequency is good. In a word, the first choice of voice is worthy of being 300B!
