POWER IN RESERVE
Cambridge Audio 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.
ALL METAL DESIGN
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.
