This page is intended to demonstrate the incredible value of our 6 Year Supercare. Under recent legislation, we are obliged to point out that you obviously do not need to purchase an extended warranty at the same time you purchase your electrical goods and are entitled to shop around. We have been encouraging our customers to do just that for years because, not only are our prices significantly cheaper than our competitors, but just look at what else we include:

Free loan machine (only if taken back to store)
Should you encounter a problem, just ask and you'll be provided with a unit to ensure you're not without music whilst your equipment is being fixed.

Like for like machine if unit is unrepairable
If, for any reason, we are unable to repair your unit, we'll replace it. Naturally, models do change so, while we can't guarantee that it will be the same model, we do guarantee that it will have equivalent specifications.

Free routine service / Maintenance checks
have your unit serviced as often as you wish, free of charge, during the 6 year period. (Normally excluded from extended guarantees).

45 day cooling off period
If you're not happy with our 6 Year Supercare package just ask for a full refund - no questions asked. After 45 days, providing no claim has been made, you can also terminate the agreement and receive a pro-rata refund.

If you use the policy in the 6 years, you'll have saved yourself tens and perhaps hundreds of pounds. If you don't use it...IT WON'T COST YOU A THING!*

* Simply return your unused Supercare policy within one month of the expiration date, and we'll refund the price of your warranty.

Over the past 20 years, Cambridge Audio have been market leaders with their range of budget amplifiers. The Cambridge A1 was one of the best selling amplifiers of all time! It is therefore with great pleasure that we bring you their latest model; the Cambridge Audio Topaz AM1.

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), a balance control and a volume knob; oh, and what you also get is superb sound quality! 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 - trust us, this is proper hi-fi at a low-fi price.

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 5 out of 5 by Fantastic entry level amp We bought this amp to start off our seperates system. The main atraction was the price - there is nothing else out there that comes close to the same quality for the cost. There aren't many features and this could be a bit of a negative but what it does, it does well. Paired with some good quality mid-range speakers and CD player it sounds fantastic. I don't see anyone doing better for the money! 22 June 2015
Rated 5 out of 5 by Good value This is great value for the money. I'm just starting over again after 50 years and it's a great way to start. 14 June 2015
Rated 4 out of 5 by Very good service. Well - what can I say: brilliant service and an outstanding delivery service. The equipment is very good supported by a factual website. 12 June 2015
Rated 4 out of 5 by No frills, but good quality I needed a new amplifier after my venerable old NAD conked out. This does the job, allowing me to play cds and vinyl (although only because I have a turntable that plugs into the aux socket - no phono). No headphone socket either, but the sound is great. 29 May 2015
Rated 5 out of 5 by Simply great sound An amplifier with no tone adjustment required because it provides a solid mid range sound losing no detail. It accepts many forms of connection to suit all equipment. It provides a slim clean fascia with the easiest style of controls to use. 27 May 2015
Rated 3 out of 5 by LOUD HUM the first unit I bought had a loud electrical hum when powered up and was very noticeable between tracks.contacted customer service and they arranged a replacement which I have picked up today(27/04/15).this unit has the same problem which is a shame as I really like the sound from this amp.i know this is a budget amp but this is not what I expect from a Cambridge Audio product.I must add the service from the staff at the shop and customer service has been excellent. 27 April 2015
Rated 5 out of 5 by Topaz AM1 as a Keyboard Amplifier Delivered on time and working well. I'm using it to amplify my Yamaha keyboard, which has only a 2.5W amplifier, and needed the volume to be turned up past half way to hear anything much. Now I only need to turn it a quarter up, and the Cambridge AM1 to about ten-o-clock, to get really good sound from my 10 inch speakers. You can hear realistic sound from the low notes of the grand piano voice, which were barely audible with the keyboard amplifier alone. A very satisfactory project .. 22 April 2015
Rated 5 out of 5 by A bargain Hi Fi amp This amp does the basics very well. It does not have many connections or features/controls, however the frankly very small sum has been well spent on delivering very good sound. Now it does not compare performance-wise to my main system's amp set-up (a pre and 2 power amp combo), but at one fiftieth of the cost I can't really complain! And top marks for Richer Sound's service and delivery company too! 21 April 2015
