1. The latest carbonized anode, the average 300B only consumes 40 watts, and the Jinyin Rhenium anode can reach 56 watts, which is much purer than the anodes sprayed with graphite emulsion or lamp smoke by other manufacturers, so the sound quality is purer and more transparent!
2. 300bk cathode emission material, with higher emission performance and oxidation resistance, can fully ensure the complete distortion of music in large dynamic.
3. The sound is clear, the sound field is wide, the high frequency is gorgeous, the intermediate frequency is full and powerful, the bass extension is strong, the details are rich, and the listening sense is very comfortable, which is better than the high-priced 300 B of other brands above 90%. The 99.999% high-purity gold plating process grid effectively inhibits the grid current, and the sound quality is by going up one flight of stairs.
