Description Product Description Style: A-S3000 | Color: Black Product Description Profoundly accurate sound with the full expressive power of the music. Exceptional sonic purity, elimination of signal loss-in an exquisite, elegant design. The supreme culmination of the Yamaha line-the A-S3000. The goal: To express the deepest emotions of the artist, to touch and move the hearts of listeners, and to deliver the utmost pleasure in the music. The S3000 series was born from this passion. In order to make this a reality, we designed the A-S3000 Integrated Amplifier literally from the ground up-returning to the drawing board of amplifier design, completely revising the chassis structure, circuit layout, and other elements-creating Yamaha's own unique Floating and Balanced Amplifier. Bringing our passion for music, our desire to provide the ultimate sonic experience, and our technological expertise to the forefront, we thoroughly refined and redefined how a top-flight amplifier should perform-and sound.

Rigid Streamlined Construction — Provides Strict Anti-vibration Protection and Enables Shortest Cabling RoutesThe A-S3000 has adopted a newly designed highly rigid double structure construction in order to achieve profoundly pure and accurate audio amplification. The bottom chassis and insulator ward off external vibration and provide each circuit board a floating structure supported by an independent inner frame, thoroughly eliminating the impact of vibration. And the power source unit, which consists of a power transformer and capacitors, which are major sources of internal vibration, is fixed firmly with a three-dimensional structured inner frame and is supported solidly by the front panel and the rear panel. The power amplifier circuit board and the weighty heat sink are attached to the left and right inner frames. The power supply unit and amplifier circuits are thus structurally isolated, achieving an ideal chassis structure which thoroughly blocks the transmission of vibration. Moreover, the inner frame that supports the power transformer is shaped with ample space below it, allowing passage of the wiring to each circuit over the shortest possible route. The newly developed chassis with this innovative structure helps to minimize the length of the signal paths and achieve low impedance, as well as providing high rigidity and anti-vibration benefits. The result is a dramatic reduction in signal loss, for remarkably pure audio amplification. Large Toroidal Transformer, Solidly Mounted with Independent Three-dimensional Inner FrameAn independent three-dimensional inner frame has been employed in order to provide a more solid mount for the large toroidal transformer, which is installed in the center of the A-S3000, considering the ideal weight balance. The completely copper-plated inner frame has a structure which integrates the front-back and left-right frames with a convex-shaped highly rigid main frame as its base, reducing vibration coming from all directions. For the base, to which the power transformer is installed on the inner frame, brass was selected by strictest examining the particular sonic properties of various materials by exhaustive listening tests. This material effectively reduces vibration caused by the power transformer, helping to create sound of greater clarity and spaciousness.
