Stereo integrated amplifier (Silver)
Our take on the Yamaha A-S2000 by Crutchfield's Woody Sherman
You can see Yamaha's commitment to exceptional sound quality in every aspect of their A-S2000. It's built from the ground up give you the best performance possible — from its innovative, fully balanced amplifier design to its rigid, anti-vibration chassis.
This integrated amplifier feeds 90 full-bandwidth-rated watts to each of your stereo speakers — you'll enjoy clean, undistorted audio, even during your music's most demanding peaks.
Fully balanced amplification
The A-S2000 features a set of balanced XLR inputs for noise-free, distortion-free audio signals from compatible high-end audio gear. Its advanced amplifier design keeps the signal balanced, completely isolating the "plus" and "minus" sides of each channel, ensuring remarkably clean, pure sound. This amp is also a great choice for vinyl lovers — it can handle signals from MM (moving magnet) cartridges, as well as from more demanding MC (moving coil) cartridges.
Use tone controls without sacrificing audio quality
Many amps offer direct modes that let you bypass tone control circuitry for optimum sound quality. But you don't have to choose between audio quality and properly balanced sound with the A-S2000. Its volume and tone controls are wired in parallel — this allows you to adjust treble and bass to your liking, without muddying your music.
A strong, vibration-resistant build
This integrated amplifier boasts a thoughtful, rock-solid design. Yamaha organized the left and right channels into a straight, symmetrical layout, keeping the signal path short and the sound clean. High-end internal components — such as extruded aluminum heat sinks and custom-made capacitors — allow the A-S2000 to handle demanding passages effortlessly. An anti-resonant base, rigid center bar, and height-adjustable steel feet provide a sturdy, vibration-resistant foundation.
Connections and convenience
This integrated amp offers enough inputs to connect six audio components, including a phono input and a set of XLR inputs for compatible high-end gear. Two sets of main speaker outputs let you connect an additional pair of speakers. Separate preamp input/line-level output jacks allow you to use the A-S2000 as an independent power amplifier or pre-amp for future system expansion. And the included remote gives you easy control of the amplifier and the other Yamaha audio components in your system.
I purchased the AS2000 because I didn't want to go the separates route. I am glad I did. It is very well built, sounds clean, clear, as if musicians and singers are in the room with you. I would purchase it again.

Overview: The Yamaha A-S2000 Integrated Stereo Amplifier features a built-in two-channel amplifier with A & B speaker outputs and seven analog inputs.
Floating Balanced Circuit Design: The perfectly symmetrical, fully new floating balanced power amplifier maximizes the performance of the analog amplifier by reducing distortion and noise.
Full-Stage Balanced Signal Transmission: The integrated amplifier offers full stage balanced transmission, combining high power output with good sound texture and outstanding S/N performance.
Independent Power Supplies: The stereo amplifier features four independent high-capacity power supplies.
Aluminum Front-Panel and Heavyweight Feet: The A-S2000 features an aluminum front-panel and newly developed heavyweight feet to suppress vibrations. The feet of this unit also include built-in spikes for added stabilization.
ToP-ART/High Current Amplification: Yamaha uses the ToP-ART (Total Purity Audio Reproduction Technology) design concept, which combines the latest and best technologies, parts, and circuit designs, to maximize sound quality. High Current Amplification uses superior quality components from input to output to achieve high current power with low impedance.
High Current Stereo Amplifier: The Yamaha A-S2000 features a highly dynamic, powerful stereo amplifier with low impedance drive capability. The stereo amplifier is rated at 90 watts x 2-channel at 20-20kHz, in 8-ohms with 0.02% THD or 150 watts x 2-channel at 20-20kHz, in 4-ohm with 0.02% THD.
Triple Parallel Electronic Volume and Tone Controls: The Yamaha A-S2000 is equipped with triple parallel electronic volume and tone controls. The stereo amplifier features independent bass (50Hz) and treble (20kHz) controls so you can increase or decrease the low and high frequency response (+/-9dB).
Note: The volume and tone controls do not effect the amplifiers Main Direct Input or Record Output.
Balance: You can adjust the sound output balance of the left and right speakers connected to the amplifier.
Trim: This function adjusts the volume level when headphones are plugged in to avoid sudden changes in volume. You can select between -6, 0, +6, or +12dB.
Audio Mute: The Audio Mute function reduce the current volume level by approximately 20 dB.
Speaker Selector: The Speaker Selector switch allows you to select only A speakers, only B speakers, A+B speakers, or no speakers; so you can control which speakers are playing.
Remote Control: The integrated amplifier comes supplied with an IR remote control for wireless operation of the unit. The remote control can also be used to control select Yamaha audio components such as a CD player or AM/FM tuner. The remote has a range of 20 feet at an angle of 30-degrees left-to-right of the unit's front-panel IR sensor.
Analog Inputs/Outputs: The Yamaha A-S2000 integrated stereo amplifier is equipped with six analog RCA stereo inputs for connecting an external audio source such as a CD player, AM/FM tuner, Turntable, and/or cassette deck; as well a preamp or AV receiver. There is also one analog RCA stereo output for recording through the amplifier.
Note: The unit's Phono input also features a ground terminal and is designed to connect a turntable with an MM or MC cartridge.
Balanced Input: The Yamaha A-S2000 features a set of balanced XLR inputs for connecting your CD player.
Main Direct Input: One of the A-S2000's analog inputs is labeled Main Direct Input. This input allows you to connect your preamplifier or AV receiver directly to the A-S2000 and use the Yamaha stereo amplifier as a power amplifier to drive a pair of speakers in your system.
Note: Audio signal coming into the amplifier's Main Direct Input is only output through the speaker outputs of the A-S2000. No audio signal will by output from the stereo amplifier's Pre-Out, Rec Out, or Headphone Output.
Pre-Out: The Yamaha integrated stereo amplifier is equipped with a stereo preamp output for connecting a powered subwoofer or to use the A-S2000 as a preamplifier and connect it to a larger power amplifier to power your speakers.
Speaker Outputs: The Yamaha stereo amplifier features gold-plated binding post terminals for its A & B speaker outputs. The speaker outputs are color-coded for easy connection. You can use the A & B speaker outputs to power two pair of separate speakers or you can bi-wire a single pair of speakers.
Note: If you use two sets (A and B) of speaker, the impedance of each speaker must be 8-ohm or higher. When only using on set of speakers (A or B), use speakers with an impedance of 4-ohm or higher.
Headphone Output: The A-S2000 integrated amplifier is equipped with a front-panel 1/4" headphone output for connecting a pair of headphones (sold separately). Once a set of headphones are connected, the amplifier's speaker outputs mute automatically.
Note: The headphones do not function for the amplifier Main Direct Input.
