Cambridge Audio TOPAZ SR20 Stereo Receiver

Cambridge Audio TOPAZ SR20 (Black)

Stereo Receiver

In stock
£349

Richer Sounds exclusive model.

With inputs for a turntable and digital sources, plus power to spare, the Cambridge Audio Topaz SR20 is the compromise-free receiver.


Power aplenty

At the heart of the SR20 is a high quality, amplifier that's powered by an oversized toroidal transformer. This sort of quality component is usually reserved for more expensive amps and gives the SR20 a class-leading power output of 100W per channel. This means the Cambridge Audio SR20 has the ability to drive a wide range of speakers to high volume levels, even in larger rooms. Two sets of outputs make it possible to run a second set of speakers simultaneously in another room, and there's a dedicated subwoofer output.

Digital inputs
With twin optical and a coaxial digital input there are options for a range of digital sources. Connect your TV, set-top box, games console, DVD player and a whole host of other sources and with a top quality Wolfson DAC (Digital to Analogue Convertor) built in, the sound from most sources will be noticeably enhanced compared to using the analogue inputs.

Plenty of analogue inputs
The SR20 has three line level inputs and an output for recording. There's also a good quality MM phono stage, so you can connect a turntable without needing a separate phono pre-amp. At the front there's an input for an MP3 player or iPod and a headphone socket. In short, the Cambridge SR20 has everything you need to form the basis of a complete hi-fi system.

Built-in radio
The tuner radio, of course, is already built-in. The FM/AM design offers 30 pre-sets (15FM/15AM) and excellent quality sound. The RDS functionality is easy to view via the cool-blue display.

Cambridge quality
Built to Cambridge Audio's usual high standard, the Topaz SR20 is also far better made than the class average. A rigid metal casing with brushed aluminium front panel looks and feels a lot more luxurious than the thin steel case and plastic front panel that's more common at this price. The full metal casing also offers excellent resistance to both electrical and mechanical interference, giving a cleaner, purer sound.


As a powerful heart to your complete hi-fi system, the Topaz SR20 is simply without rival.

Rated 5 out of 5 by from Good looking with a sound to match I have been upgrading my system over the last 6 months and I now have Cambridge Audio Topaz CD5 CD player Cambridge Audio Topaz SR20 stero reciever Cambridge Audio SX60 speakers Teac turntable All the above was purchase from Richer sounds, I am so impressed with the sound, the whole system only cost around £800, Friends and Family who hear the sound cannot believe how detailed it is. Latin Quarter swimming against the stream sound frantasic on CD and Vinyl. I strongly recommend richer sounds and Cambridge Audio.

Rated 5 out of 5 by from Very patient salesman Returning to vinyl after many years. Listened to various equipment in Richer Sounds and decided I liked the sound of this, I am not disappointed in my purchase.

Rated 5 out of 5 by from Great amount and affordable The amp is great. It's simple enough to look good. The sound is brilliant through my KEF Q750 with plenty of power. RicherSounds had the best price by £50.

Rated 4 out of 5 by from great sound the unit is a good basic amp, which worked well with my JBL 250 watt speakers, and my turn table went strait in without a pre amp. it is not fitted with a network connection but I think this can be added.

Rated 5 out of 5 by from Great Sound, Great Features Bought this as an upgrade to my Yamaha RS202D after reading the reviews, have to say I am not disappointed, it has all that I need in features and the sound is great, I use it with a Denon DP300 turntable and Mordaunt Short M20 speakers. Volume is good and all round sound is great. It does not have DAB but that was not a deal breaker for me as I normally only use FM. I would recommend this piece of kit without hesitation.

Rated 5 out of 5 by from Topaz sr20 Good amp I had a Yamaha a-501. this amp is far better, sounds really good I am really pleased with this
