Summary: I bought this Yamaha A-S1000 never before heard an amplifier, so I read many reviews and opinions from people who bought and decided by Yamaha. I use a tower of RX6 Monitor Audio, and offers 105w rms in 6 ohms. A Player Onkyo, and other Pioneer. The sound is clean, clear and detailed, not strident like some people say, is very balanced and dynamic. I used cables from Van den Hul, and were excellent. Optimal buying this Yamaha, and I hear pop and rock and sound is great.
Summary: There's no doubting the high quality of the design, aesthetics, and sound of this extraordinary amplifier. My only objection concerns the ironically few inputs on the rear panel--an engineering drawback which I've awkwardly gotten around by resorting to television switching boxes with four or so extra inputs, etc.
Landmark audiophile quality with superb attention to detail and intuit

Summary: The beauty of this integrated amplifier extends across multiple dimensions. Physically the design is elegant, with apparent interest in ease of operation core in the mind of the designers. It weighs in at a hefty 48 pounds which is indicative of the massive transformers enclosed in its elegant casing. Upon setting this up for the first time in my home and playing the first songs a grin of total exuberance came across my face-the sound was an audio experience to behold.
Pros: High performance, audiophile quality, completely ergonomic, looks, feels and works as if no expense was spared.
Cons: Beware it is about 3 inches deeper than most other units and may be tough to fit into some cabinets.
Summary: This unit might cost more if produce by others small manafacturer,
Pros: This unit is very good, have enough power to drive my THIEl speakers, highly recommended for anyone like details music, simple stereo system, there are a big different in sound coming out of this unit than many others all in one receivers, I could hear the high, mid, bass, very clear, when it come to selecting audio equipments, the heavier the unit weight the better, and this unit is very heavy. You know that yamaha use high quality parts in this unit.
Summary: I bought this amplifier as the heart of 2.0 hi-fi kit for our listening room in Japan. I've also bought the CD-S1000 and matched them with Monitor Audio's GS20 floor standing speakers (which are absolutely sublime). I had the opportunity to audition this amplifier along with about 30 - 40 other units at one location so narrowing down the list did take some time.
Summary: Excellent build quality and superb sound. Rivals all of my older 70's and 80's high quality amps/receivers in side by side comparisons. This amp was meant to replace my aging Yamaha 2020 Receiver for a satellite system, but I was so impressed that I moved it to my main system and enjoy it every day. I am very pleased with the unit in every way. Nice to see that Yamaha has returned to offering a higher end product line.
Pros: High quality, excellent build, good fit and finish. Plenty of power
Cons: Would have preferred silver face, but it appears to no longer be available.
Summary: For me, this integrated Yamaha amplifier produces powerful and detailed sound through my Martin Logan stereo setup. It connects easily to my turntable, but I use it most often with a ps audio DAC connected through coaxial to a Sonos Connect as my audio server. It is also connected to an fm/am NAD tuner which also produces awesome sound on the Yamaha a-s1000. I could not be happier for the price compared to functionality amd performance.
Pros: Powerful detailed sound, quality of build, heavy, good looking, functional basic controls on face plate and remote.
Cons: Volume knob is a little loose. Generic flimsy power cord.
Summary: I was not finding myself pleased with most amps under $3500, but didnt have that amount available. After reading some reviews decided to try the Yamaha as1000 as it's sheer weight difference with the AS 700 signaled it was obviously the beginning of serious quality upgrades in the Yamaha line-up. The unit is beautiful, and the sound was beautiful in terms of timbre.
Pros: Exceptional beauty and purity of tone, exceptional build quality. I think quibbles about quality of knobs must be references to lower models. Rear binding posts are gorgeous.
Cons: Lacks drive and grip in absolute terms that can make it sound slow on certain recordings of rock, jazz, things that need drive. Not terrible in these areas, just not at same level as the rest of the sound. Main caveat is that even recognizing these slight weaknesses, I find myself missing this amp.
