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.

Designed for European ears

At the heart of this European sound-tuned amplifier are features to create a dynamic and well-balanced sound. High-current transistors and a high-capacity power supply circuit give the PMA520 a powerful, punchy sound, while clean, short signal paths and improvements to the volume circuitry help it sound 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.

Vibration-resistant design
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 helps reduce 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.

Plenty of features
Despite its focus on sound quality, the PMA520AE still has more than enough features. For those with record decks there's a built-in phono stage, plus four line level inputs and a recording in/out loop. Tone controls, a headphone socket and a 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 5 out of 5by excellent budget amp For the money this is an excellent amp,it has a good solid build quality and a great sound, my only complaint's are that the light indicating the input selection is way to bright and that the posistion marker on volume control is not highlighted with a different colour,otherwise an excellent purchase. 11 April 2016
Rated 5 out of 5by Very good item This unit gives an impressive performance at this price point. I doubt you would find anything better at the price. 15 January 2016
Rated 5 out of 5by Excellent punchy sound, clear, crisp definition and a beautiful tone - very happy indeed. I wanted an amp to partner my new turntable, and as the Denon has a built-in phono stage and gets good reviews, I chose this. It is superb - build quality is very high, it is weighty & substantial, and paired with Q Acoustics 2010i speakers it gives incredible sound quality and range. With my Denon CD player taken back out of the loft and plugged in, I'm re- discovering the joys of old favourites - Home Alone never sounded so good! It has a built in power supply, too, so my turntable takes up one less socket. Excellent punchy sound, clear, crisp definition and a beautiful tone - very happy indeed. 19 December 2015
Rated 5 out of 5by Unbeatable for the price My ancient Sherwood receiver hooked up to my Sky and TV developed a fault where the the volume knob motor was stuck in "turn up" mode (not good), so needed an inexpensive replacement. Paired with some old but great B&W speakers, this Denon amp sounds amazing, with a great amount of bass and detail, and goes really loud without any problems. I'm very happy with my purchase, and Rosa at the Preston branch was great :) 05 November 2015
Rated 5 out of 5by Wonderful sound I have several Denon products and needed an amplifier for a music room where I have a Yamaha DVD/CD player and a pair of Heco speakers. My old Yamaha receiver had expired. I am so pleased with the unit. I am no expert but the sound is great and for what is offered the price is very good. All arrived as promised. Very seamless. 20 October 2015
Rated 4 out of 5by was reconditioned and still had faults th eone i had was reconditioned and hadnt been repaired properly but when working not bad . 06 October 2015
Rated 4 out of 5by Sound purchase for the money Looks good (as if that matters) and operates well. Sound is pretty good bearing in mind the cost - I'd dropped from a Cambridge Audio A640v2 to this and can tell the difference but as the 640A has packed up and I'm getting bored of mid-range amps promising the world I thought I'd try something cheaper and I'm not disappointed.I've not tried the phono stage (and probably won't as I've a Cambridge Audio phono amp). Remote is ok for the money. Only niggles are the cheap looking transformer that can be seen through the casing (and there's no way I'd run another device off the back 240V outlet), and the remote is far easier to use than the dial selector on the front of the amp. 08 September 2015
Rated 3 out of 5by Hmm... I bought this product along with the Wharfedale diamond 9 speakers. The sound is adequate but I wouldn't rate them higher than that and I picked up some Panasonic RP-HH225 headphones too. Soon as I rigged up the amp and speakers I thought it sounded okay, nothing special. Through the Panasonic headphones the sound is muffled at best. My advice would be to invest in better speakers and headphones if your budget allows. To be honest I am pretty disappointed with the set up but what do you expect for just over 200! 31 August 2015
