旗舰系前级725，引入Z新的电源技术，令725具有比前任旗舰系前级720更惊人立体音质，无Y伦B的丰富细节，令人难以置信的低频冲击力，失真及杂噪进一步下调。全新的电源技术，经彻彻底底重新设计，电源系统工作更精确，调节更精确。滤波电容总量比720多出400，000μF，带来几近无限脉冲电流之仿真电路。

Due to the new power supply technology the 725 preamplifier has an even more breathtaking three-dimensional sound quality than its predecessor the 720 already did. Unsurpassed wealth of detail. Incredible punch at low frequencies. Distortions and noise could be reduced even further. The preamplifier is the command centre of your high fidelity chain. In tests its sound quality has proved to be second to none.

 

The 725's totally redesigned power supply unit works even more precise and regulates more precise and faster than the power supply of the 720. With more than 400'000 µFarad of storage capacitance it provides almost unlimited impulse current for the analog circuits.
