In this video, I’ll give you a complete review of the Yamaha A-S701 stereo integrated amplifier. You’ll learn about its tech specs, some of its interesting features, and I’ll give you all the info you need to answer the question: should you buy one?
Hey, if you enjoyed this hi-fi related video, please SUBSCRIBE to my channel, HandyAndy Tech Tips! I normally do computer-related content (including tech news and how-tos), but, if enough people are interested in this video, then I might produce more videos on stereo components, including my bookshelf speakers!
NOTES on the Yamaha A-S701:
– So, it’s a stereo integrated amplifier. That means that it provides amplification for mainly analogue sources, and it has no media streaming, touchscreen, or even AM/FM tuner.
– In fact, this harks back to the 1970s and 80s, both for its design and features. For one thing, there’s no display on the front of the unit, just a series of controls. Want Bluetooth? No way. Fancy connecting an iPhone or your PC via a USB connection? Nope.
– This is an audiophile product, and its specifications and features reflect that. Just its weight gives you an indication of how high-quality it is: it weighs 11.2kg.
– Inside, there’s a custom-made power transformer, custom made capacitors and two enormous aluminium heatsinks.
– On the front of the device itself, you’ve got a power button and a headphone jack. However, this accepts 1/4 inch headphones, so you might need an adaptor if you want to use your 3.5mm cans.
– You’ve then got your speaker selector, and this ties in with the rear connections. It accepts two different pairs of speakers, or you can bi-wire a single pair.
– Continuing, we’ve got the bass and treble controls. These are a bit unusual because the bass control applies a +/-10dB boost/cut at 20Hz, and the treble control a similar range but at 20kHz. Usually,
these types of controls boost at 100Hz and 10kHz, respectively.
– Then there’s Yamaha’s famous continuous loudness control. This makes the sound more realistic when you’re listening at low volumes, because the human ear seems to pick up more midrange and less bass and treble in quiet sounds. It attentuates at 1kHz by 30dB.
– The input control gives you a choice of three line inputs, which are standard RCA. You also get optical and coaxial; you can input up to 192kHz / 24-bit via an integrated DAC. Then you’ve got an analog in for a CD player, input for a tuner, and also a phono input, which automatically applies the RIAA eq curve to vinyl records.
– CD DIRECT AMP gives a direct signal path from the CD input, bypassing the tone controls for a sound that’s cleaner and less degraded. PURE DIRECT does essentially the same thing, but it works for all inputs, not just CD.
– Gives 100W of power through both speakers with 8 ohm resistance at 0.019% total harmonic distortion (THD).
