300B Sound Description:
1: vocals, violins, light music and other playback is quite sweet, while the bottom of the sound has a certain thickness, high-frequency transparent and delicate, low-frequency is not very exaggerated, the strength is still possible.
1: vocals, violins, light music and other playback is quite sweet, while the bottom of the sound has a certain thickness, high-frequency transparent and delicate, low-frequency is not very exaggerated, the strength is still possible.
2: 300B has a unique sound field, some people say called overtones rich, the pair of amplifiers sound like a little reverb, the sound field is larger, a good sense of stereo.
3: Three frequency articulation natural, loose sound. Personally, I think the 300B sound coloration is larger, listen to what is with a little sweet, but very pleasing to the ear.
4: The details of the high frequency is very good, the midrange is prominent, the low frequency is good. In short, the first choice for vocals, worthy of the king of the vacuum tube 300B!
