Black Stereo Amplifier

  • Often manufacturers don't just design their ranges to look good together, but to complement one another for the best sound quality too.
  • The quiet signal that comes off the needle of a record player needs the extra boost of a phono stage to be heard. This unit has one built-in, though an external unit may well offer better quality.

With a long-held reputation for superior budget amplifiers, the Denon PMA520AE comes with impressive pedigree.


At the heart of this European sound-tuned amplifier are a number of technical features that help create a dynamic yet well-balanced sound quality. High current transistors and a high capacity power supply circuit help give the PMA520 a powerful, punchy sound. Designed specifically with wide frequency sources, such as SACD, DVD-A and high bit rate streaming formats in mind, the PMA520AE has been thoroughly engineered to make the most of these revealing media. Clean, short signal paths and improvements to the volume circuitry have helped the PMA520AE sound even more precise and articulate. The fully discrete amplifier stage and separate analogue power supply ensure fine detail is faithfully reproduced and distortion is kept to a minimum.


With its solid metal casing and large, anti-vibration feet, the PMA520AE is well equipped to resist sources of mechanical interference. The aluminium front panel also helps in reducing electrical interference, especially from sources such as light dimmers and fluorescent bulbs. As you'd expect from Denon, the quality of finish is impeccable, with smooth edges, solid construction and well damped controls.


Despite its focus on sound quality, the PMA520AE still has more than enough features. One welcome feature for those with record decks is the built-in phono stage. In addition to this there are an extra four line level inputs and a recording in/out loop. Tone controls, a headphone socket and a full, system remote control makes up a strong spec.

With its smooth, powerful sound, unrivalled construction quality and useful range of features, it's hard not to see how the PMA520AE could be anything other than another impressive budget Denon amp - a tough act to follow.

Rated 4.7 out of 5áby 7 reviewers.
Rated 4 out of 5áby Excellent value for the price I have just received this amplifier, set it up and tried it out in all sources and I am very impressed. It is definitely a budget amp but certainly in the upper range and sound a lot livelier than the amp it replaced, (Arcam Alpha 7) Having tried Turntable, Tuner, CD player, Computer and internet I would recommend this amp. 22 April 2015
Rated 5 out of 5áby Excellent value for money Excellent value for money. Its solidly built, 'feels' quality, and sounds #to my ears anyway# superb. It has a phono stage as well which means I'm getting reacquainted with my 70's/80's album collection! I'm sure spending 3 or 4 times as much would get you better sound - if you had the speakers and the cd player to do it justice. But for day to day stuff, using old Kenwood speakers and my PC as a cd player - its perfect. 25 March 2015
Rated 5 out of 5áby Very good quality amp I had to buy a new amp as my Rotel was playing up.I already have a denon dab tuner which is very good so i purchased this from Richer sounds for ú220 approx. I did not relalise how heavy it is (7kg) so had to beef up my stack shelves,but apart from this it just slid in.When connected it had excellent bass and treble,whether from radio,cd or vinyl. I have tannoy 100watt speakers and i find it better with the loudness button off,and just ajust the bass treble to suit my ears. All in all a very good well built amp with plenty of distrotion free sound, Highly recommended *****. 24 March 2015
Rated 4 out of 5áby This is a great budget amp I don't have anything to compare this amp to. I bought it because I wanted to start playing my collection of LPs which have been in the loft for the last ten years again. So far I have not been disappointed. Although this is classed as a budget amp, I think I've got a bargain 17 March 2015
Rated 5 out of 5áby An amplifier that lets the music shine. The DENON PMA520AE produces a fine, natural, detailed and pleasing sound with great presence, making the most of the material from a wide range of sources to provide an enjoyable listening experience. It is solidly built without compromise. It has proved to be tremendous value for money to someone needing a new amplifier, which I did fortuitously ; a very reasonable price to pay to hear a music collection afresh. 06 September 2014
Rated 5 out of 5áby value for money Brilliant amp. Dont know much about all things amplifier but this does job and doesnt dissapoint. Using it for my 1210's and happy to get the vinyl sound again. Delivery fast. 21 September 2013
Rated 5 out of 5áby use to high end gear,linn, naim. this is for loft/gym use. burned in, sounds open and controlled. get's me in the right mood for a work out. powering a pair of gale 3010s speakers, with symphony 400 cable. the sound is open and tight. you won't get a lot of bass with these speakers, as they are small. very pleasant to listen to. headphone jack good, used in loft/gym. would probably get more bass if wanted from a larger speaker and i'm sure the amp would do the job. remember: source-amp-speaker. 10 July 2013
