Pre-amplificatore phono MM / MC commutabile -elevata precisione e disturbo ridotto - chassis inalluminio e acciaio - filtro subsonico per eliminaredisturbi nelle basse frequenze causate dalleimperfezioni del vinile - controllo bilanciamentoper le testine Whether you’re dusting off your record collection or embracing analogue through the vinyl revival, there’s a unique experience to be had from the moment you drop the needle on your favourite album. To preserve the unique warmth of the vinyl sound, the Duo phono preamplifier has been carefully designed with a state-of-the-art switch mode power supply and a new surface mounted circuit board layout to reduce unwanted noise. WHY CHOOSE A DEDICATED PHONO PREAMPLIFIER? Due to the low-level signals created by a turntable, not all hi-fi amplifiers will let you connect directly to a record player. The phono preamplifier boosts this signal to something a power amplifier can work with. The challenge at this stage though is that noise can easily be added. This is why we’ve designed the Duo around exceptional components that deliver the warm and detailed sound that’s synonymous with vinyl, all without distorting the signal from your moving magnet cartridge turntable. The switch mode power supply improves performance by switching outside of audible frequency to drastically reduce hum and new circuit board layout uses surface-mount components to reduce noise. VINYL. JUST FOR YOU. Enjoy the warmth of vinyl privately thanks to Duo’s integrated headphone output. Uniquely, we integrated a 6.35mm headphone jack directly into the phono stage, so you can still enjoy your records when there’s no option to play out loud. The integrated headphone output also means no need to turn on your amplifier just to power your headphones, resulting in a more eco-friendly listening experience. ATTENTION TO DETAIL If some records in your collection are a little worse for wear, the subsonic filter will help to eliminate low frequency rumbles that can be caused by imperfections within your vinyl. Combine this with the balance control for handling potential cartridge imbalances in your record player (that can cause a difference between the left and right channels) and the result is a detailed experience with accurate soundstage. ECO FRIENDLY The Duo phono preamplifier is green at heart with less than half a watt standby power consumption and auto power down feature if the unit isn’t used after a 20 minute period. This in turn gives the unit the same worldwide voltage for compatibility wherever you are in the world

The signal processing of cartridges is one of the most delicate jobs in amplification. All the more so because it isn’t done merely by boosting a few hundred microvolts to a few hundred millivolts. In fact, at this thousandfold amplification (60 dB) the signal must be processed as cleanly and noise-free as possible. The extremely low signal level and the frequency-dependent amplification which arises from the RIAA equalisation curve applied in the cutting of LPs make the highest demands of the circuit topology and technical realisation of a phono preamplifier.

Our award-winning QUASAR phono stage, with its discrete conception and wide range of features, meets the requirements of even top-class turntable/cartridge combinations without being “unreasonable” in the usual high-end fashion.


The QUASAR is built in dual-mono configuration from the power supply upwards. There are two separate amplifier stages for MM and MC cartridges, both being fed from their own regulated power supply arrangement. Optimum adjustments to the MC cartridge in use can be applied for sensitivity and load by various settings of the jumpers on the PCB. The two separate outputs with different output levels make it possible to fine match for preamps or recorders.

The output stage has huge headroom at extremely low noise levels and, due to its low output impedance and high current delivery, can drive long interconnect cables without any sonic degradation.

The enhanced power supply of the QUASAR, the Q-PSU that also can be used as power supply upgrade with other components, is based around a 50 VA toroidal transformer with low-density magnetic field and very little dispersion. This power, together with a fine voltage regulation system, can feed the circuit with the kind of super-clean current usually delivered only by battery-based supplies, even with extreme dynamic swings.

Today, many amplifiers do not have a specific phono cartridge input. Phono Box E is an ideal phono preamplifier for these hifi systems. Phono Box E accepts MM cartridges and offers an audiophile music experience at an entry-level price. Advanced circuitry and SMD construction keep noise and distortion at a surprisingly low level. A built-in internal shielding and an outboard DC power supply leave no risk for external interference. Because of its small casing, Phono Box E can be placed near the turntable. Input and output sockets are gold-plated for preservation of quality. Phono Box E can be connected easily to a line-input (AUX etc) of your amplifier.
