Product Description

Manufacturer's Description

When it comes to amplifiers, Pioneer's line up offers sound options that make music sound better than ever. Pioneer amplifiers are what the dreams of audio lovers are made from - innovative high performance components with extra features and additional connections to all types of speakers and home entertainment systems. Amplification without distortion and stable sound localisation leads to what you want: pure sound.

The A-109 is a 40-Watt integrated amplifier that adds a stabilizer for the transformer and chassis. And its symmetrical design results in excellent stereo imagery. The A-109 is among those Pioneer amps to feature the Direct Energy MOS FET transistor directly linked to the speaker output. Efficient input signal transmission with minimum distortion requires the signal path to be as short as possible. The highly efficient Direct Energy MOS FET allowed Pioneer to develop its Advanced Direct Connection, with a shorter signal path and ground line and Symmetrical Construction. This combination ensures that left and right channels are clearly separated and have the same impedance, giving ideal stereo reproduction with identical sound quality. These two design concepts ensure more stable stereo sound localization and a rich sound field.

Was looking for a decent starter amp for my son and did not want to spend a huge amount of money. Owner of 'higher level' Denon and Cyrus so was not expecting much for £100, but very surprised at results. Sound impressive for such a low cost unit and quality of finish and functions offered good. Very good purchase if looking for low cost amp in comparison to what else is out there. Bought on the back of other reviews on Amazon and can only agree. Excellent value for money.

I have only just received this amp, hence the "initially" prescript. I bought the Pioneer A-109 as a replacement for an old Sony amp. This new amp was easy to install and came with UK power adapter as well as European connector. Initial sounds are really good and, for the price, has a great clear sound. The amp is basic, has phono and is manually operated (no remote) the amp is ideal for what I wanted as a second amp to support my computer and the Rega deck for my vinyl. It provides a great sound out of my "old Leaks"

Bought this to replace my NAD 3020 AMP of 28years which finally packed in.
My initial feeling on this amp was that of great disappointment, the sound seemed quite 'muddy' on some of the tracks that I was playing. The cymbals on Africa by Toto were very poor.
But 4 weeks down the line I am actually very please with it, the afore mentioned cymnbals on Africa are now very good, and the general sound is no longer muddy.
I could'nt understand this improvement but have done some googling and found that amps need time to burn in.
For the money it appears to to do a good job and though there has been a vast improvement over the last few weeks I am still not convinced that it is better than my old amp.

I bought this amp to use in my loft, connecting a turntable and DAB component (Cambridge Audio) unit. What an excellent bargain! Lovely rich sound from my Marantz turntable again, great performance definition and depth from the amp, using the built in pre-amp/phono stage. DAB sounds great, too. This performs way above what the price might indicate.

No remote control provided but none needed in my case. Unlike other reviews here, a UK plugged mains cable was included in the box (as well as the standard euro 2-pin).

The unit looks to be well built so hopefully it'll be in place for a long time to come.

I have owned this amp since last october and have been amazed by the sound quality. It has all the inputs you could wish for and it feels well built. Don't be put off by the slightly lower price tag if you are a hifi lover on a budget you can't loose out here. I own units by lots of different brands like Denon and marantz, this amp can sing with the best of them and give more expensive products a run for there money just buy it and enjoy

Happy Listening :)

I wanted to replace a very old Trio Amp for my play room. I think there is alot of rubbish talked about Hi Fi in general & I believe that the weakess link in any system are the speakers, which can be a very personel thing. I didn't want to spend a lot of money on an Amp so I went for well establised name like the Pioneer A-109. It does everything that I would expect it to do. I have it connected to a Denon Tuner, an LG CD/DVD, a Yamaha Keyboard & a PC all piped through a pair of Wharfedale Diamond 9.1 speakers. They all sound terrific.

If you want a really great amplifier but you're a student, or you don't want to spend a fortune on an amplifier, than this is the amp for you! It gives a rich and clear sound. And no one can beat the price!
The only downside is the lack of support for a second pair of speakers, if you don't mind this, then go for it!

For the money, this is a really excellent amplifier from every point of view except one, it does not have a remote control. If you don't need a remote, GO for it!
