TopazSR20
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.
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 RESERVE
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
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.
