The Cambridge Audio Topaz SR 20 is a very well featured and powerful stereo receiver from a company with a great heritage in providing great hifi sound since 1968.Their products are constant award-winning quality that offers great value and they keep getting better at it.
For over 50 years Cambridge Audio has been refining their technologies in their quest to truly reproduce "The British Sound".They define "The British Sound" as audio in its purest form.....not "mucking about" with the sound at all.Their Topaz SR20 receiver follows this design formula to optimise the pure analogue sound of playing vinyl.
This receiver delivers 100 watts per channel,quality watts powerful enough to give good drive capability to almost all loudspeakers to give you great live sounding dynamics.As well as impressive power, the SR20 displays impressive control - using Cambridge Audio's "Sound First" design principles, they've maximised audio quality and minimised cost and clutter. In the SR20 that means they use toroidal transformers, usually only seen in high-end separates, to more accurately channel that extra power.Cambridge Audio believe, for instance, that multi-channel surround sound codecs and terminals in a hi-fi amp at this price adds complexity, introduces noise and reduces the budget for key components. That's why the SR20 is a pure stereo amp. And that means better sounding music. After all, your music is their passion.
The SR 20 also covers most bases when it comes to connecting all your favourite sources. It accommodates your turntable for the atmospheric vinyl experience with an inbuilt phono preamplifier and being a receiver,it has an inbuilt AM/FM tuner.And then there is the digital input stage incorporating an onboard high quality digital to analogue converter which allows you to connect your TV to your hifi system via digital optical......the only way late model TVs output their audio signal.Then there are the extra digital inputs to allow digital streaming,etc. and an extra 2 analogue inputs for other components.There is also a direct MP3 input conveniently located on the front panel for smartphone music streaming.Combine this with a dedicated subwoofer speaker output for improving bass and two sets of speaker outputs and there is plenty of flexibility for system expansion.
The Cambridge Audio SR 20 stereo receiver is truly a special sounding piece of kit.There is no question—this is classic British sound. It just lets the music flow through. Bass is extremely tight and well defined, while still keeping the music together. You’ll be tapping your foot to the music in no time.A great way to enjoy all your sounds with high fidelity sound for an exceptionally reasonable price.The SR20 is perfect for today’s music lover. Couple it with a good pair of speakers and you’ll have a great stereo system, but it can do so much more.
Wolfson WM8728 digital-analogue converter for connecting digital sources
100 Watts of AB amplification through a toriodal transformer for huge power and volume
A dedicated subwoofer output to make the SR20 the heart of a 2.1 hi-fi system
Built-in MM phono stage allows direct playback of turntables
Two sets of fully switchable speaker outputs mean you can enjoy fully independent A/B switching of two pairs of speakers
Thanks to it’s onboard Wolfson DAC (Digital to analogue converter) the SR20 provides three digital audio inputs, allowing the connection of digital sources such as streamers, TVs or laptops and it will then play them all with incredible detail and depth.
Continuing the comprehensive specification and attention to detail, the SR20 features a built-in MM Phono stage, bringing your vinyl to life! Turntables fitted with phono cartridges of either the Moving Magnet (MM) or high output Moving Coil (MC) type (between 2-6mV output and 30-50k load impedance) can be used.
POWER IN RESERVE
Cambridge Audio strive for audio perfection, which is why SR20 features a powerful toroidal transformer. They were one of the first manufacturers to use toroidal transformers in the 1970s, and they continue to use them today. Some of the benefits of a toroidal transformer, over the cheaper, inferior EI transformers used by most other manufacturers are:
High quality power output to the amplification circuits, with no clipping, transformer noise, buzz or hum, to provide a consistent signal
High power output, to allow large and demanding speakers to be driven at high volumes with sensational bass performance
Large power reserves, to allow the transformer to deliver high peaks of volume when required
Fully shielded against internal and external electrical interference, to maintain quality of power and signal
ALL METAL DESIGN
Electronics (and therefore sound quality) are particularly susceptible to vibration; that’s why they’ve used a low resonance, acoustically-dampened metal chassis to eliminate as much vibration as possible, ensuring that the most sound quality is extracted from every source.
The Cambridge Audio SR 20 stereo receiver is truly a special sounding piece of kit.A great way to enjoy all your sounds with high fidelity sound for an exceptionally reasonable price.You will struggle to find a better value for money solution to achieving quality sound and connectivity at this price.It does tick the boxes.
