[FULLY DISCRETE NFCA ALSO CREATE WONDERFUL AMP]

As its name, A90 Discrete uses fully discrete component to redesign the NCA (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 parecision matched transistors in the design ensured the unparalled distortion and noise performance.

[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.

[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.

[A Headphone Amplifier, also a Preamplifier]
The A90 Discrete is not only able to drive the headphones but also served as a preamp. When it's in preamp mode, you can get the same high performance as the heapdhone amp mode and the 20ohm SE and 40ohm BAL 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.
