Topping A70 Pro, musical renaissance

The Topping A70 Pro introduces, for the first time, the T'ang-ku-la module, developed by the brand and utilizes a new three-stage feedback circuit. Further reducing noise and high-frequency distortion, the dynamic range rises to a new unparalleled realm of 147dB.

The new technology greatly reduces heat generation, which greatly improves reliability, extends the life of electronic components and reduces thermal noise.

New re-optimized circuit

The newly developed ultra-low noise input stage further improved the noise performance of the balanced input and increased the input impedance to 20 kOhms, allowing it to have better compatibility with incoming devices.

The gain architecture has also been redesigned to further reduce noise and distortion in high gain states than the previous architecture.

Uncompromising power

With 17000mW of output power at 16 Ohms, the A70 PRO is able to maintain its low distortion levels.

32 Ohms headphones: 1000mW x 2
300 Ohms headphones: 1200mW x 2

Disappearance of noise

When multiple devices are used in combination, ground loop noise may be encountered. A70 Pro adds a GND/LIFT switch, when ground loop noise is encountered, switch to LIFT and the noise will disappear.

New interface

The interface of the Topping A70 PRO has been revamped to include a display with capacitive buttons and color indicators to clearly visualize everything that is going on in your amplifier: volume management, measurements, gain, etc.

Through its robust in construction and soft in touch volume wheel, you can execute all possible functions.

Independent volume control

The A70 Pro uses networks of relays and resistors to form the R2R volume control module, which provides precise volume control, long life and does not drift even at low volume.

At the same time, the device can memorize 8 separate and automatic volume settings and return to the last used volume the next time the output is selected.

Expandable inputs

The A70 Pro has one set of balanced XLR inputs and one set of single-ended RCA inputs. But with the Ext90 input expansion, you get a total of our balanced XLR and two single-ended RCA inputs.

Low noise level

The Topping A70 PRO offers excellent performance at both high and low gain. With an output voltage of 50 mW, the A70 Pro achieves a much higher dynamic range of 106.3 dB.

Also preamplifier

The Topping A70 Pro handles headphones well and can also be used as a preamplifier. It has the same high performance as the headphone amp mode, with an RCA output impedance of only 50 ohms and an XLR output impedance of only 100 ohms, allowing it to be used with a wide range of input impedances for various power amplifiers.

12V Trigger

The A70 Pro has a 12V trigger input and output interface, which supports other devices to turn on and off, as well as triggering other devices to turn on and off synchronously.

The best tandem

The Topping A70 Pro and D70 Pro SABRE have identical design languages and can meet the needs of the vast majority of active headphones and loudspeakers. The A70 Pro and D70 Pro SABRE can be switched on and off together via the 12V Trigger connector, allowing the A70 Pro to be synchronized with the D70 Pro SABRE for automatic or manual switching.

Reviews

Excelente Compra.

En la gama media, media-alta, este amplificador es de lo mejor. Lo uso en combinacion con el DAC E70 Velvet (también en Zocociy) y el resultado es excelente. Tanto con los auris (Ananda SM, Sigva 023, HD600, etc) como preamp de los Adam Audio autoamplificados. Estoy realmente contento con el resultado. Ahora...¡A disfrutar!

Espectacular

La calidad, sin duda alguna, es excelente. No sabía si comprar este amplificador junto con el D70 pro Sabre, o si decantarme por un RME ADI2 FS. Al final me quedé con el stack Topping y parece que ha sido una decisión acertada. Para mi este stack es mi "endgame", así que espero que me dure mucho años. Lo pedí ayer y lo recibí hoy; el servicio de Zococity es de 10. ¡Mil gracias!
