be used in all types of audio or audio/video systems.
Design and construction
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.
