The Cambridge Topaz AM5 takes the excellent AM1 as its basis and adds desirable extras to make an even more impressive amp.

'Sound first' philosophy

Like the AM1, the Topaz AM5 has been designed from the ground-up to offer the best sound quality for the money without any unnecessary frills. So no fancy equalizers or flashing lights but you do get high quality, low-noise tone controls. These have been designed to work in a subtle way so as not to unduly affect the balance of the mid-range, yet still tweak the upper and lower frequencies.

Detailed, true-to-life sound
With 25W per channel, the Topaz AM5 is 25% more powerful than the AM1, which makes it the ideal choice for using in larger rooms or with power hungry speakers. As with other Topaz products, the sound is true-to-life, detailed and has far more depth than similarly priced low-fi. If you don't believe us, come in and hear the difference for yourself!

Front-mounted MP3 socket
The AM5 is also far better built than the class average. A full metal casing with brushed aluminium front panel gives the AM5 the look of an amp costing two or three times as much. There's also a front-mounted 3.5mm socket that's perfect for connecting your MP3 player or iPod.

For genuine hi-fi at a bargain price, the Topaz AM5 demands your attention.

Rated 4.6 out of 5áby 31 reviewers.
Rated 4 out of 5áby An excellent budget amp... This amp seems to have a very good overall sound balance with excellent clarity and is a good replacement to my older NAD amp that has finally blown it's main reservoir capacitors after serving a 20 year sentence! The tone controls on this amp do not permit very large changes in the bass and treble values and are notched at the mid-way point so it is easy to identify a neutral sounding position. There is good inrush protection on this amp so you don't get a sizable 'thump' from the speakers when switching on (the old NAD amp was rather bad at this!). It's a bare wire connection at the terminal posts - shame as I think banana plugs are a much better way of preventing unintended shorts etc. Would have preferred a detachable power cord (AM10 and higher have this) but otherwise cannot grumble - considering we paid a similar amount for an entry level NAD amp 20 years ago I think this is something of a bargain... 08 September 2015
Rated 3 out of 5áby Unit hums - what is happening to Cambridge Audio quality control? Great budget amp, but like a couple of other reviewers, the thing hums - badly. Not the signal, but the unit itself, and it's audible if you like quiet music! Now I know it's a budget amp - but the only thing wrong was the actual humming. And I had to buy a different amp instead and pay ú70 extra. A real shame. 02 September 2015
Rated 5 out of 5áby Excellent Amp Connections are easily worked, excellent sound. Bass and Treble features work very well. 22 August 2015
Rated 4 out of 5áby Great value for money enrty amp Based on numerous favourable reviews I originally bought a Denon PM520 as a replacement for my a (very) old Cambridge Audio A1 but I was very disappointed. Fortunately, thanks to the fantastic service of Richer Sounds I was able to exchange the PM520 for this Cambridge Audio AM5 which to me is a far superior sound experience. To my ear, the Cambridge offers excellent clarity and detail, which provides an involving and enjoyable listening experience. I use this amp with an old Philips CD player, Denon tuner, and standard computer line output for MP3s, with wall-mounted Tannoy speakers. 06 August 2015
Rated 4 out of 5áby Good quality and value Nice amp, high quality sound, MP3 input useful for me. 13 July 2015
Rated 1 out of 5áby fundamental design fault - not worth paying even ú120 for This amplifier has a very audible mains hum. This is a very perceptible, continual noise even when you are playing no music. We exchanged our unit at Richer Sounds for another one, but that one had the same problem. It made no difference whereabouts in the house the unit was plugged in, or whether the speakers were connected; the noise is from the unit itself. It does seem that there must be a design fault in the Cambridge Topaz AM5 amplifier. 09 May 2015
Rated 5 out of 5áby Great Small and tidy ..record deck stands nicely on the top. Produces a great sound with straight forward bass and treble knobs. All we need. Very good. 26 April 2015
Rated 5 out of 5áby Knock-out little amp (with a big sound)! Originally intended as a ?stop-gap?, after retiring an old/ailing amp - so freely admit got this without even reviewing it first. However, is a very pleasant surprise - punches way above its weight and price-bracket; energetic/punchy but is also balanced and articulate. Easily drives/manages my floor-standers and presents a very distinct, clear and stable sound-stage. I may well end-up keeping for a while. As usual with CA gear, case and controls very solidly made. Am convinced CA stuff - especially amps - offer a sound quality that can?t be matched at (even twice) the same price. Confirm only available in black. Lack of remote no hardship. It does take banana-plugs - capped with those stupid Euro-reg bungs, but you can easily pull them out with your finger nails. QED Silver Anniversary XT works very well with this amp, distinctly resolves more detail than QED Original (also a good cable). Don?t bother with the QED crimped plugs - just get standard (screw-grip) banana-plugs. 22 April 2015
