More cryo research in audio......

From EnjoyTheMusic industry news today:

Italy based company S.A.P. has been conducting continuous research and development with the University of Europe (Politecnico di Milano) and have applied for new patent. Beginning three years ago concerning applying a special cryogenic technique (using nitrogen) to to audio and video amplifiers, SAP found that the self generated noise in all the semiconductor devices is very much depending upon the working temperature. This long-term investigation study is said to clearly demonstrated that signal/noise ratio is improved, while the frequency spectrum distribution of the noise changes significantly when cryogenic technics are implemented.

To quote S.A.P.'s Vincenzo Fratello, "In our opinion, while it is possible to reach the same result in terms of S/N measurements with other and more traditional techniques, it is not possible to obtain the same sound purity (directly connected to the frequency spectrum of the noise) with any other traditional existing methods." More applications are said to follow within microphones and other electronic devices. Demonstrations are planned during the upcoming Top Audio & Video show in Milan.
