This is a really nice power amp ! From a non smoking home. Very clean and working perfectly. Here is a video of the amp working (pre amp in video is not included) https://youtu.be/PuTWK4s3Oa0 From the manual: The ST2140 utilizes high quality electronic circuitry to achieve an environment wherein a detailed, transparent, and highly musical sound can be realized. The high quality parts complement include state-of-the-art solid state devices, 1% metal film resistors, computer grade electrolytic power supply capacitors, and a high capacity toroidal transformer. The ST2140 operates class A predriver and AB high current MOSFET power output stages. It is capable of reproducing the most demanding audio signals at rated power levels. Features Toroidal Transformers - Efficient high current transformer for improved dynamics. Discrete Circuitry - More accurate and three dimensional reproduction of source material. Class A Predriver - Improves low level detail for smoother, more musical sound. AB MOSFET Output Stage - For efficient and linear power delivery. Limited Protection - Provides short term protection from accidental shorting of output devices and protection from thermal overload. Gold Plated Connectors - Improve connections for better sound and minimized signal loss and degradation. 1% Metal Film Resistors - Low noise resistors for better sound and a greater degree of repeatability. High Current - Ability to reproduce demanding recordings. Computer Grade Capacitors - Large capacity computer grade electrolytic capacitors for extended low frequency control and improved dynamics.
