What kind of experience is it when you make a vacuum tube that may be the best sound on earth?

Five years ago, when we decided to create an Acme series of audio vacuum tubes, there were countless visions for us. Like the spirit of the Voice of Nobility, our pursuit is not only the abundance and satisfaction brought by the material. We sincerely hope that the Voice of Nobility will become one of the few respected sound manufacturers in China, and also hope that we will be the same as every fancier, whether upstream or downstream，always full of passion and joy for vacuum tubes, audio, music, and life.

As a flagship product for many years, the reproduction classic series has been filled with praise from all walks of life to the Voice of Nobility.The one who want to walk ahead, the opponent is only himself---the most powerful opponent.

We know well how hard it is to make a masterpiece go beyond a hundred years of classic products, but in order to live up to the original intention and also live up to the expectations，we must go on with confidence and patience.

While mind understand thoroughly will be wisdom,and wisdom understand thoroughly will be virtue

The development and manufacture of vacuum tubes is always a multi-disciplinary and complex field, We are in awe of it, but does not mean that we are reluctant to move forward. This time, we chose to subvert the once highest honor podium: to gather the development team at home and abroad and develop the flagship product with independent intellectual property, meantime together with the understanding and accumulation of technology by Voices of Nobility, this is the Acme series.
