Over the past 20 years, Cambridge Audio has been market leaders with its range of budget amplifiers - the Cambridge A1 was one of the best selling amplifiers of all time! So we're proud to bring you its latest model, the Cambridge Audio Topaz AM1.

'Sound first' philosophy

Designed from the ground-up, the AM1 is a no-frills amp with just the basics, but the best sound quality possible. There are no tone controls or fancy equalizers, no flashing lights or unnecessary sockets. What you get is four line level inputs (1 with output), balance control, a volume knob, and superb sound quality!

High quality internal components
By cutting back on the extras, Cambridge Audio have managed to retain high quality components. Connect your MP3 player or iPod, CD player, PC and TV and you'll enjoy a true-to-life sound quality that's leagues ahead of similarly priced multi-media speakers. This is proper hi-fi at a low-fi price.

Built to last
Like other Cambridge Audio Topaz models, the AM1 is also far better built than the class average. A full metal casing with brushed aluminium front panel gives the AM1 the look of an amp' costing two or three times as much.

Genuine hi-fi doesn't get any better value than this!

Rated 4.7 out of 5áby 80 reviewers.
Rated 5 out of 5áby Excellent sound and cheap as chips! Richer Sounds have always marketed cheap amplifiers with excellent sound - I had a Cambridge A1 many years ago - and this in no diffferent. With an aged Sony CD player it has blown away the all-in-one unit I had before. 11 April 2016
Rated 5 out of 5áby Great budget amplifier I bought this as a stop-gap for a short time and I'm very impressed. The features are limited to the very minimum (4 channels, only volume and balance controls, no 3.5mm or other inputs) but the build quality and the sound quality are excellent. I would definitely recommend this for anyone working to a very strict budget. 06 March 2016
Rated 5 out of 5áby budget amp is great value who needs VU meters, base and treble controls when all you really want is a powerful mellow sound 28 February 2016
Rated 4 out of 5áby Excellent value stereo amp Perfect for a first amp and quality home listening. - Thanks :) 17 February 2016
Rated 5 out of 5áby Ignore the 'budget' tag.. My ú500+ amp suddenly developed a weird fault, switching the sound between speakers, left, right, left, right like a frenzied drill sergeant, so whilst deciding between repair, extended therapy or taking a chainsaw to the thing I decided to buy this 'budget' amp as a stopgap because as Nietzsche said: ?Without music, life would be a mistake.? I'm absolutely blown away by the sound of this amp, it definitely sounds better (to these ears) than my ex-amp which cost 7 times as much. It reminds me very much of a quite expensive Musical Fidelity amp I once had, and perhaps that's the point - all the most expensive amps eschew flashing lights, remote controls and the like to deliver better quality sound, just as this does It's only 20w per channel (my ex amp was 75w) but it's driving my Tannoy MX3's effortlessly. I'm listening to every one of my albums again and saying 'Wow' a lot. In short: marvel at the price, be grateful for it, but don't judge the amp by it.. 15 February 2016
Rated 3 out of 5áby Good sound quality This was very easy to connect to our turntable and speakers. The sound quality is very good. The only downside to this product is its not very loud, the volume is turned fully up and it is only loud enough for background music. This is ok most of the time but not if you have a few people round and also some types of music need to be played a little louder, I don't wish for it to be blasting out but a little louder would have been better. 31 January 2016
Rated 5 out of 5áby CAMBRIDGE AUDIO TOPAZ AM1 Bought this amplifier for an elderly relative. Ordering and delivery were excellent experiences. The basic controls on the amp are well suited for the intended recipient. That doesn't mean that the sound is basic though, for it is rather good and better than the amp it replaced. An excellent buy. 26 January 2016
Rated 5 out of 5áby You get what you pay for. Probably not the best amplifier in the world, but what would you expect for ú80? Simple, basic and does the job. I'm pleased with it. 20 January 2016
