    Sugden Audio’s new Masterclass ANV-50 integrated amplifier is at Musicraft (Derby)

    As the Masterclass ANV-50 integrated amplifier is part of the Masterclass Series, it has gold plated circuit boards as standard. This pre-amplifier board also uses high quality silver plated PTFE wire for the signal connections, like all our Masterclass products.

    Renaissens reviews Sugden Audio's new Masterclass ANV-50 integrated amplifier

    "This type of newer installation is commonly called "switching power supply" or SMPS."

    "Its big positive point is that the transformer remains very modest size and that its realization will be easy. The rest of the diet is however more complex and requires stronger expertise; this is precisely the pattern chosen by the Sugden team for feeding the ANV-50 and it's a first at Sugden."

    "In the diagram, we find here the diode bridge and the filter stage which are upstream, this time. After these stages, a DC voltage of approximately 320 V is obtained."

    "The whole game consists in supplying from this DC voltage a square signal to the primary winding of the transformer. The frequency generally found on this type of power supply. varies between 60 and 120 kHz. There are oscillators (PWM) that "spin" at 200 kHz on the best amps. Sugden designed for the ANV-50 a 1MHz oscillator! We can therefore expect an unusual current capacity."

    "The ANV-50 is fast as lightning and restores a wider sound spectrum especially in the bass. It also highlights a lot of details ...."

    "With the ANV-50 we are immersed very quickly in the music. This experience is similar to that of the concert as the readability is great. What depth, what fullness. We stopped after 13 good minutes, because we had to ... We could have gone on for a very long time ..."

    "The ANV-50 offers a remarkable operating silence and a micro-dynamic omni present that are to fall! Bravo!"

    "With our entire drivetrain ANV-50 no phenomenon of this kind. The contours are incredibly sharp, no pumping phenomenon, the percussions are restored with a natural, a level and a variety amazing. Congratulations again!"

    "By developing this unique cutting-edge power supply, Sugden's engineers bring new possibilities to the A-Class."

    "It will be perfectly in place on many speakers including large speakers particularly greedy current. We were especially amazed by his musical follow-up and of course by his extraordinary speed."


    The Masterclass ANV-50 power output module is a unique design with high current capabilities. Because there is no current limiting it can drive a 1 Ohm load with a flat frequency response from 10Hz – 100 kHz. The power supplies have short circuit protection and no electrolytic capacitors to degrade over time.

    The company was founded by James Edward Sugden in 1967, a division of Research Electronics. Research Electronics manufactured scientific instruments and test equipment, designed by James Sugden, for Universities. The A21 was the first amplifier to be put into production and was originally branded for a well known local loudspeaker company called Richard Allan.

    Sugden Audio. The best of British.

    The Masterclass ANV-50 is a sophisticated integrated amplifier with some unique circuit designs. But like all Sugden Audio amplifiers, we like to keep things minimalistic when it comes to operation. The hardware we use is high quality and chosen for durability.

    The Masterclass ANV-50 is an all new design with unique circuitry. As it is an integrated amplifier, it has a pre-amplifier and two power amplifiers. The pre-amplifier circuit has been designed to use a minimum number of high quality components and is developed from Sugden Audio's flagship pre-amplifier the Sapphire DAP-800.

    In 1967 Sugden released the world’s first solid state pure class A amplifier, the A21. The ANV-50 promises to revisit this golden age of British audio engineering, with a design focused on the demands and preferences of today’s audio enthusiast and music lover.

    The ANV-50 has at its heart, the purest class A amplifier Sugden Audio has ever produced and this is coupled to an advanced ‘ideal’ final output stage. This unique two stage amplification system guarantees our signature pure class A sound, with the ability to drive most loudspeaker systems.

    The sophisticated final output stage features a comparator and correction circuit so that errors which could occur in the power output section due to varying loads and distortion, are corrected to match the output of the high impedance input amplifier. Whilst maintaining the signal authenticity, it also increases the load stability and forces the output impedance to zero. This special output stage with Sugden Error Correction has extremely low open loop output impedance with a resultant high damping factor at quite high frequencies. It also benefits from overall Current-Feedback.

    The power amplifier and pre-amplifier are fully DC coupled so there are no capacitors in the signal path to interfere with or deteriorate the sound quality. One of the key features of Sugden Class A amplifiers is the power supply. Because they have a high standing current and power reserves, the output is always ready to act instantly to any signal. This is unlike a conventional Class AB amplifier that waits to receive power through a transformer and a bridge rectifier. The ANV-50 takes this one step further by using a 1 MHz switching power supply which acts instantly to deliver the power as the Pure Class A amplifier section is always on.

    The power supplies are high current, fast and incredibly stable. With a MTBF (Mean Time Before Failure) of 100 years they are designed for longevity and reliability.

    As the ANV-50 is an integrated amplifier it has an internal pre-amplifier, developed specifically for this amplifier. The circuit is a line drive design and uses the minimum number of components, all of which are high quality. This provides a very open and natural sound and demonstrates that when carefully engineered, less can be more.

    When the ANV-50 does not receive an input signal it has a very low power consumption of only 20 Watts, making it extremely efficient. As the heat sinks are mounted internally with minimum contact to the outer case it only runs slightly warm to the touch.

    Loudspeaker matching with the ANV-50 should never be a problem. With an output of 50 Watts into 8 Ohms that can double in to lower impedances, room size and loudspeaker sensitivity becomes less of an issue so a much larger range of loudspeakers can be enjoyed.

    Sugden Audio's A21 Signature Line and Integrated Amplifier -

    The Sugden pure class A design provides affordable high-end performance from a beautifully engineered single box integrated amplifier. Compact in size with a simple but stylish design, the A21 is possibly the only amplifier you will ever need. With many of the original A21’s still in daily use after fifty years, it could also last a life time. Providing a large soundstage and depth to all types of music, the A21 is an amplifier you can listen to for hours without fatigue. The single ended voltage rail circuit provides impressive dynamics and incredible bass.

    The A21 Signature integrated amplifier is available with or without a MM/MC phono input. Without a phono input it is designated the A21L (line input only). A21aL models can be fitted with a phono input at a later date.
