Topping A90 Discrete Headphone Amplifier

Topping A90 Discrete Headphone Amplifier

The TOPPING A90 Discrete is a high-performance headphone amplifier and preamp featuring fully discrete NFCA modules for unparalleled clarity. It delivers high output voltage and current to drive any headphones with ultra-low distortion. Get it today from Gears for Ears the official dealer in the country at the best price in Bangladesh.

Ground Loop Noise Terminator

Ground loop noise may be encountered when multiple devices are used in combination. A90 Discrete adds a GND/LIFT switch to solve this problem. When in normal use, set it to GND; and when ground loop noise is encountered, switch it to LIFT. Then the ground loop noise is eliminated.

High output voltage, high current, low output impedance, no headphones that can't be dealt with

High output voltage can easily drive high impedance headphones; High output current allows low-sensitivity headphones to obtain enough power; The low output impedance will not bring unnecessary effect on FR when driving low-impedance headphones. Different headphones can be easily driven by the A90 Discrete.

Fully discrete NFCA also create wonderful amp

As its name, A90 Discrete uses fully discrete components to redesign the NFCA (Nested Feedback Composite Amplifier) module. 4 built-in NFCA-Discrete modules which each them uses 39 transistors build up fully balanced structure. The optimized Voltage Current hybrid feedback architecture along with UHGF (Ultra High Gain Feedback) technology provide excellent DC and AC performance. Benefiting from the new design, the output capability is stronger than ever, which allows the amp driving low impedance headphones even more effortlessly. The paralleled ultra low noise precision matched transistors in the design ensured the unparalleled distortion and noise performance.

2 Gain settings

The A90 Discrete has two gain options, which enough to cover a wide variety of headphones: low gain to drive the IEMs with high sensitivity, and high gain to drive full-sized over-ears. Combined with the 0.2uVrms ultra-low noise, even sensitive IEMs will not suffer from any noise.

Low distortion while outputting high power

In addition to the high output power, the A90 Discrete can maintain ultra-low distortion output under high power load.

A Headphone Amp, also a Preamp

The A90 Discrete is not only able to drive the headphones but also served as a preamp. When it is in preamp mode, you can get the same high performance as the headphone amp mode, and the 20ohm SE and 40ohm balanced output impedance are widely suitable for various power amplifiers. A90 Discrete can not only switch between the headphone amp (only output from the headphone jack) and the preamp (only output from RCA and XLR), but also support the output from all at the same time. The full-featured remote control makes it more convenient for you to use.
