Product Highlights

    Superior Audio

    In keeping with our famous "Sound First" audio principles, Cambridge's audio–obsessed engineers have insisted on using premium components throughout in a quest for perfection. The Class AB amplifiers and toroidal transformers, usually only seen in highend separates, offer stunning music reproduction and minimal distortion. And both receivers use the same discrete output stages as our Azur AV receivers costing many times more.

    Topaz SR20 Powerful Digital Stereo Receiver

    The SR20 is the most powerful amplifier in the Topaz range offering an immense 100 watts per channel, backed by a dedicated subwoofer output as well as two sets of speaker outputs. It also features analogue inputs, digital inputs, a phono stage, an FM receiver and an MP3 input, so it will connect and play virtually anything you throw at it.

    Digital Connections

    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.

    Vinyl Perfection

    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 Serve

    Cambridge Audio strives for audio perfection, which is why SR20 features a powerful toroidal transformer. CA 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.
