Do things better now，don’t ask the future 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.

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.

As the only one modern audio vacuum tube which with retro-onion glass shell styling (Acme 300B, 274B, 2a3, etc., ) all over the world, it is very beautiful from both inside and outside, tribute to the Centennial Classics; Benefit from improvement of the support structure after comprehensive consideration of the stress and harmonious vibration relationship , Acme
