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.

Electronics (and therefore sound quality) are particularly susceptible to vibration; that’s why we’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.


We strive for audio perfection, which is why SR20 features a powerful toroidal transformer. We were one of the first manufacturers to use toroidal transformers in the 1970s, and we 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
