Cambridge Audio A1 Integrated Amplifier

Cambridge Audio A1 Integrated Amplifier
Cambridge Audio

When you think of true budget hi-fi, you think of Cambridge Audio. For years now Cambridge Audio have been manufacturing and selling pieces of hi-fi such as the A1 integrated amplifier by the lorry load. The A1 Intregrated Amplifier is a true a budget classic, well made and with a sound quality that puts many amplifiers at more than twice the price to shame.

Available almost exclusively through Richer Sounds in the UK, the A1 originally sold for just under £100, fifteen years in and you can still pick one of these gems up for under £80. For an extra £20 pounds, you can be the proud owner of an A1 Special Edition, purposely designed for the UK audiophile with improved circuitry and torroidial transformer for a cleaner power supply.

The A1 comes with four line inputs, a moving magnet phono pre-amp can purchased for an extra £20. A tape monitor is also included and there are treble, bass and balance controls but that is it.

Sound quality of the A1 mk3 SE is quite detailed and warm but never harsh and bass is quite tight and rythmic. Only when you compare it against superior integrated amplifiers such as the Audiolab 8000A can the imaging and soundstage start to sound a little muddy and confused but this a sub £100 amplifier. I used about 6 years with a couple of TDL Nucleus 1 Loudspeakers to amplify a computer soundcard with great success. I now use it to drive the surround speakers in a 5.1 surround sound system using a pair of Eltax Silverstone 110 bookshelf speakers..

At 30 watts per channel into 8 oms, the Cambridge Audio A1 may not be the most powerful amplifier in the world but ideal for a starter budget system or for use in a secondary system in a small room. The Cambridge Audio A1 is probably best matched with a speakers who have a sensitivity in the region of 86-90db due to the power output.

In short a true classic budget design that should impress even the most demanding of ears.

This amp is a classic. Lovely sound, simple design and my one is still going strong after the best part of 10 years. It's only let me down a couple of times, through overheating at house parties, but it's not really meant to be on full volume for six hours with poor ventilation.

What a beaut.

I have an A1mk3 & need a moving magnet pre-amp to engage the turntable. Where can I get one? I am in The Netherlands & can only order online/mail-order.

I bought my CA A1 Mk3 about 3 years ago as my first proper hi fi gear. Love the sound, and had it hooked up to a Denon DCD 695 CD with B&W DM 601s. A lovely warm sound and brilliant value. I have since replaced the CA with a Rega Mira 3 amp (though not got rid of the CA A1 amp.).

I am now thinking of getting a CA 340 C or perhaps even a 640C to hook up to the A1 and B&W speakers. While upgrade the speakers for the Rega Amp.

This amp has a nice crisp and warm sound compered with other solid state amplifiers. I think cambridge audio A1 MK3 SE is far better than the Nad C320 and considering it's price, this amp is a real bargain. Hook it with two second hand vintage Kef speaker (coda) and the sound is brilliant! Strongly suggested for budget oriented customers.

Cambridge Audio A1 Mk3 - driving a pair of Tannoy Cheviots with NAD C545BEE Cd player. With sensitive speakers you don't need a lot of power. Sounds good to me 10 years on.

Matthew,

By default, the phone input is just a line level input, you need the MM module that is an optional extra. Best bet is to keep an eye out on Ebay, as Richer Sounds stopped selling them a while back.

thanks very much. What exactly is an MM module and does it work with the amp & turntable? Also, how much should I expect to pay? Sorry for all the Q's and thanks again!

I've had the A1 amp for 9 years now, and i use it daily. never broken down or had any troubles bar a slightly dim power indicator and a fuzzy volume pot at high levels.

Sounds fab powering my Tannoy Reveal 6 reference monitors :D

Cambridge Audio A1 MK3 SE is a real hi fi bargain! rich and detailed sound with a wide soundstage. Far better than its competitor Nad 320, this amplifier will give you hours of real music pleasure!

Hi

Just got my Cambrdge Audio A1 in a pawn shop nearby home for only 10 Canadian Dollars. Before plugging my vintage speakers in (sansui S-917c acoustic suspension) I checked the output and the the left channel was indicating around 28 volts DC. This was a fault and Ichecked out the power transistors but these were correct and then the pre-drivers and there it was... the BC 639 was open. Just replaced it and discovered the lovely and warm sound coming through my speakers. I think it's a top amp and for those looking for a good amp I recommend to take a serious look to it because it is a serious amp...

For those having trouble shooting with their Cambridge Audio A1 just check the pre-drivers BC 639, may be it is a common fault or weak spot in these amps.

Hi

What about to use a pair of Boston Acoustic A26 with my Cambridge Audio A1? Should they match well? Thank you

I have an A1 v3 driving a pair of Tannoy Venus MKII's. I was only intending on using the A1 as a temporary measure but 1 year in and its still in the rack. Says it all really. re pre-amps I use a Project - The Phono Box. Its sounds great and will do MM and MC.
