We have tested the Yamaha R-S700 stereo receiver!

Yamaha was founded in the early 1900s by Torakusu Yamaha. Since then, their product range has been constantly expanding and the brand enjoys great popularity among audio and hi-fi fans.

Design and features


The Yamaha R-S700 stereo receiver has an aesthetic appearance and the front of the case is made of aluminum. Thanks to the Pure Direct function, the signal travels in the shortest way from the input to the speakers. It also has a stepless Loudness function for optimal sound.

The housing of the receiver is designed to be completely isolated from ambient noise, and its rugged design also reduces vibration. It is also equipped with an AM / FM tuner and you can tune in to 40 favorite stations. The turntable input also allows you to listen to classic records. Together with the two pairs of speaker connectors, all connectors are gold-plated.

Externally, it looks like a standard black stereo receiver. On closer inspection, however, its simplicity is reminiscent of old stereo integrated amplifiers.

It was quite a surprise to us during the test that the digital audio input for the CD connection was missing. The only way to connect a CD player is to use analog stereo RCA cables.

There are two features worth highlighting, one is CD Direct Amp and the other is Pure Direct. Pure Direct mode directs signals directly to the amplifier, bypassing the processing process. CD Direct Amplifier mode generates a balanced signal from the input source and sends it directly to the receiver.

Additional features of the receiver include an unusually high attenuation factor, the 240, and the front / main sockets. The sockets allow the user to connect an external processor and use the R-S700 as an receiver only, or to connect an external receiver and use the R-S700 as a preamplifier / processor only.


As for the attenuation factor of the amplifier part, the instruction manual prescribes 240 attenuation factors at 1 kHz and 8 ohms. According to the manufacturer, this is actually the “linear damping factor”. Why linear? The attenuation factor is the ratio of the input impedance of the speaker to the internal impedance of the receiver. For a given speaker impedance (say 8 Ohm), the lower the impedance of the amplifier, the higher the attenuation factor. However, the input impedance of the speaker varies within the audible spectrum, so the speakers are given a “nominal” impedance value. Thus, the attenuation factor may also vary within the audible spectrum. A “linear” attenuation factor means that the attenuation factor is either constant in the range of 20 to 20,000 Hz or never falls below a certain value. In fact, the R-S700 has a damping factor of “240 or more”.

YR-S700-remote controls

The R-S700 comes with two remote controls, one for each zone. The Zone 2 remote control is much smaller and infrared. An extra remote control is not essential, as the main remote control can control any zone. The main remote control itself is adequate but not outstanding. The buttons are small, the design is not ergonomic at all, and none of the buttons have a backlight or night light. The buttons and text are so small that they are difficult to read without direct light. The range of the remote control is acceptable and the buttons, although small, work well

The R-S700 is a powerful receiver, considering it’s just a stereo device. The components in the R-S700 are symmetrically arranged. Yamaha claims that this symmetrical design allows for “accurate sound field reproduction”. The “ToP-ART” – “ART” part refers to the design of the Yamaha chassis, which they claim eliminates the effects of external vibrations.

Setting up the Yamaha R-S700 stereo receiver

Setup is complete in seconds. I connected the Klipsch Forte III speakers, the Sony BDP-S6700 blu-ray player (which now served as a CD player) via analog connections.

For the R-S700, separate amplifiers are used for the tweeter / midrange and subwoofer parts of the two-way speakers. The R-S700 also has a subwoofer output. There is no bass handling, so if you decide to use a subwoofer, you will need a built-in, adjustable low-pass filter. A high-pass filter would also be good for the main speakers, but it is less necessary.

The R-S700 also has an energy saving function that can be set or turned off. It is basically a sleep timer with three options: 4, 8 and 12 hours. When the power save function is on, the receiver turns off if it is inactive for the set time.

The test

We tested the stereo receiver in a whole large music and movie room. The room was square, with broadband acoustic panels and wooden cubic diffusers placed on the walls for a balanced and clear sound. To reduce external noise and improve room acoustics, soundproof acoustic curtains were placed in front of the window and door. Although the settings of the receivers can be used to improve the sound, acoustic control of the rooms is essential to create the perfect sound quality.

The FM radio sounded pretty good. This was followed by CD listening. We tried several musical styles. The music was unadulterated and appropriately neutral. After turning on the CD Direct Amp mode, we experienced better sound. The R-S700 delivered sounds with plenty of power and dynamics. There was no noticeable distortion or noise, even when we listened to the music at high volume.


This stereo receiver has accurate, dynamic, clear and pleasantly neutral sound. Its price is also favorable compared to other two-channel receivers, but at the same time it is capable of fair and powerful production. We did not hear distortion at even higher volumes. If you want a good-sounding, strong receiver and don’t want to get into debt for designing a music or movie room, the Yamaha R-S700 may be the right choice for you.
