The TOPPING A90 Headphone Amp is the companion for the highly reviewed TOPPING D90 DAC. It is already receiving rave reviews on Audio Science Review. The A90 is an ultra high-performance headphone amp that can also work as a pre-amp. It comes with three gain settings and has great performance numbers including <0.00006% THD+N, 145dB DNR, <0.2uVrms Noise, <0.1 ohm output impedance, and 7200mW x 2 max output power.

 

The A90 comes equipped with NFCA modules (Nested Feedback Composite Amplifier), which along with ultra high-gain feedback technology provide excellent AC and DC performance. High output current capability of the A90 allows it to drive low impedance headphones with ease. Furthermore, ultra low noise of 0.2uV and high dynamic range of 145dB drive the most sensitive IEMs without producing any audible noise or dark background.

 

For outputs, the A90 comes with a 4-pin XLR, a 4.4mm Balanced, and a 6.35mm Single Ended port. The Single Ended 25V pp with Balanced 49V pp high output voltage along with high output current and less than 0.1 ohm output impedance, A90 is compatible with a wide range of headphones. It also comes with the three-step gain setting and a wide variety of sensitivity settings that allow the amp to drive sensitive IEMs to power demanding headphones.

 

Being equipped with NFCA modules, A90 can also work as a pre-amp. In pre-amp mode, the 20ohm single ended output and the 40 ohm balanced output impedance make it easily compatible with various power amps. You can also connect the A90 with the D90 DAC in pre-amp mode to drive active speakers and create a high-performing sound system.
