TOPPING A50S

Ultra-High Performance NFCA balanced modules

A50s uses the same NFCA (Nested Feedback Composite Amplifier) module from flagship A90. Voltage Current hybrid feedback architecture along with UHGF (Ultra High Gain Feedback) technology provides excellent DC and AC performance. High output current drive capability allows the amp driving low impedance headphones with ease. Ultra-low noise of 0.3uV is miles ahead of the competition, giving an absurdly high dynamic range of 144dB and no audio noise and darkest background for the most sensitive IEMs.

2 step gain settings, adapt to various sensitivities

A50s is equipped with two gain settings of 0dB/6dB at SE output(6dB/12dB at balanced output). Wide range of gain settings and the 0.3uVrms ultra-low noise makes A50s easily adapt to all types of headphones from extremely sensitive IEMs to most power demanding full-sized over-ears.

Also an excellent preamp
The NFCA modules of A50s are not only able to drive the headphones but also apply to be a preamplifier with the same ultra-high performance. When it is in preamp mode, output impedance is as low as 20ohm, which is widely suitable for various devices.

HPA/PRE automatic switching
When the A50s is not connected to any headphones, it automatically works in the preaplifier mode, and the amplified signal is output from the RCA on the back panel. When the headphone is connected to 6.35mm or 4.4mm output, A50s automatically switches to the headphone amp mode, and The signal is only output to the 6.35mm and 4.4mm jack.

Full Aluminum case
A50s uses full aluminum case with unique workmanship. The outer casing is made of an aluminium brick through CNC precision machining. The outer casing is designed with thermal conductive column to dissipate heat from the power supply and OP-AMP through the entire outer casing.

6.35mm SE & 4.4mm balanced output
Although there is only a single-ended input, A50s has a built-in balanced amp circuit. Therefore, it can drive single-ended headphones by 6.35mm output, and drive balanced headphones by 4.4mm balanced output.

Wide range of adaptation to headphones
A50s has a high voltage swing of 42Vp-p, power of 3500mW per channel when both channels are driven and output impedance of less than 0.1 Ohm. It easily drives power-hungry headphones with a wide range of different impedance.

CORREZIONE RECENSIONE PRECEDENTE

Confermo quanto scritto nella recensione precedente ma mi sono accorto che ho erroneamente dato un punteggio di solo 4 stelle quando volevo in realtà darne 5. Mi scuso con Playstereo.

Ottimo amplificatore cuffia

Ho comprato l'A50s dopo averne letto in rete le recensioni. E' quasi perfetto, soprattutto se si considera il prezzo. Ha un'ottima capacità nel mettere in luce i riverberi, gli echi, i piccoli dettagli che creano ambienzae profondità nelle registrazioni. L'alimentatore dedicato èdovrebbe fargli fare un ulteriore salto in avanti.
Servizio e la velocità di Playstereo eccezionali come sempre.
