Review: What a great piece of gear this is, I retired a long in the tooth Jolida tube amp in desperate need of a full recap for this. No hum or distortion out of this unit, just puer smooth power. Pushes the Polk XT70s beautifully. Also rear B+W bookshelf speakers and never breaks a sweat. No cooling fan required. Im Running it through a Yamaha EQ70 equalizer. And it just pushes clean quiet power. The amp functions flawlessly, with a soft mute feature. When a LP is done press mute, the volume lowers to a just audable level, push it again when your ready and it slowly ramps up to the previous preset level. There is no blutooth but thats an easy fix for 20 to 30 dollars buy a add on box and plug it in. Overall value is very good on this. You get a lot of head space for your buck. Im Running Polk XT70s and B and W 603s all 8ohms ,the rear swith set to high power, and this amp is 100% clean, powerfull and dosent even flinch or get warm. Review: I preface this review letting everyone know to give this amplifier a week to open up from a sound perspective. That has been my experience before making an assessment: Aesthetics: 4/5. I like the minimalistic look of this amplifier. However, I dislike Yamaha's decision to make tone controls rectangular. That decision baffles me actually, because many people who are critical of their audio sources tend to have OCD, like myself. Round tone controls would have made more sense. I purchased a black amplifier in order to avoid the asymmetrical look of the tone controls while in use. Build Quality: 5/5. At this price point, considering it is the 21st century, I find the build quality acceptable. It's on par with the Technics sl-100c. This means that even though this Yamaha may not be built as sturdy as in the past, it's still pretty good considering the price point and the century we live in. If one is looking for build quality from the days of yore, one will have to pay many times as much for a new amplifier. Note that if one is expecting an fm radio/tuner, they will have to buy it separately. Sound Quality: 4/5. This portion of a review will always be subjective. Normally, I have always enjoyed an open, lively sound. This amplifier doesn't meet that criteria. However, it has it's own unique sound, which when paired with the right equipment, can become addictive. This amplifier may not present all the sound details that one may be used to, but it manages to accentuate the details that matter. The sound is very clean, and I have heard details on occasion that I haven't noticed before. I must note that I don't use this amplifier for digital music. I only use it for vinyl playback and optical on occasion. The internal phono preamp is not that bad. Vocals sound fantastic. It definitely is not noisy, and records in worse condition can sound better through this unit. Perhaps that is why it may not sound lively at times; in order to produce less static and noise, Yamaha may have done this on purpose. I think Yamaha could have produced this amplifier without a phono preamp, and let folks decide on which one to purchase in order to better suit their tastes. In conclusion, I think this amplifier may appeal to those who are interested in a good, but different sound. I think Yamaha could have hit it out of the park with this product, if for a lower price the tone controls were round, and an internal phono preamp was not included. Still, I am enjoying the different sound that this amplifier produces. ## Features - A – Yamaha S501BL natural sound Integrated stereo amplifier (Black) ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00MXUCRG0 | | Batteries | 2 AAA batteries required. | | Color Screen | No | | Customer Reviews | 4.4 4.4 out of 5 stars (172) | | Date First Available | September 15, 2014 | | Is Discontinued By Manufacturer | No | | Item model number | A-S501BL | | Output Wattage | 180 Watts | | Voltage | 0.5 Volts | ## Images ![Yamaha A-S501 - Image 1](https://m.media-amazon.com/images/I/51-JWPmnHaL.jpg) ![Yamaha A-S501 - Image 2](https://m.media-amazon.com/images/I/514Re48ByaL.jpg) ![Yamaha A-S501 - Image 3](https://m.media-amazon.com/images/I/51t7vj+wVlL.jpg) ## Questions & Answers **Q: Why usually a stereo amplifier costs more than a stereo receiver with much more options and similar spec?** A: Right now, Amazon has the RS500 for about $200 less than the AS501. Given the similar model designations, you might think the "RS" designator is the receiver version of this integrated. However, dig into the specs, and you'll see it's not the case. This unit has higher RMS power (85 W vs 75W), lower distortion (0.019 vs 0.04), and specs like peak power, SNR, and freq response are not provided for the receiver (presumably because they're not worth noting). You also need to look at how power is calculated. Manufacturers are notorious for cheating AV receiver specs by reporting power over very narrow bandwidths (sometimes just a single freq!) whereas the power for this integrated unit is over the entire usable bandwidth. So, in short, the specs are not identical. **Q: Do these amps have a quality headphone amplifier that would be able to properly drive headphones with a somewhat high impedance? Ex. Sennheiser HD 650** A: The headphone jack is connected through a voltage divider to the output of the power amp and its impedance is about 450 ohms. This guarantees that HD650 will have a bump in the vicinity of 100 Hz, the headphones’ resonance frequency, which will be hard to correct with the amplifier’s bass control. For headphones, I have a separate DAC/Amp pair (Topping D30 and JDS Atom). **Q: Does the Yamaha A-S501 have a pre-amp out? If not, can one of its two recorder-outputs be used in lieu of a pre-amp out?** A: The above answers are somewhat confusing, here's a straight forward answer : IF the external amp is a 'power amplifier', the answer is NO, you cannot use the rec out output as a preamplifier. Power amps always output at the rated power, say 300 watts rms. You will blow yr speakers. Examples of power amps would be the Crown XLS and the Benchmark AHB2. They have no controls, and you need a true preamp to use them. Not this unit. Now, if the external amp is a 'variable amplifier', the answer is YES, you can use the rec out as a makeshift preamplifier. Variable amps always have a volume knob, or control, which, of course, controls the power of the amp. A good example of this would be the Topping LA90, one of the best made. Keep in mind that if you decide to use the rec out output, you will bypass the tone controls and volume of the integrated amp. And yes, the phono input and selector switch will work just fine, no worries. Finally, the AS501 is a splendid unit, why use an external amp at all? If you need more power, simply buy the 701 or 801 and sell that external amp! Anyway, hope this helps. **Q: Are the knobs plastic or metal?** A: All knobs are plastic. I own this unit. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Review *by S***R on February 4, 2026* What a great piece of gear this is, I retired a long in the tooth Jolida tube amp in desperate need of a full recap for this.
