Topping A90D

Yes, the A90D is designed to handle a wide range of headphones from 16Ω to 600Ω. With a power output of 9800mW at 16Ω, it provides more than enough headroom for even the most demanding high-impedance models.

Yes, it comes with a dedicated remote control. This allows you to adjust the volume and navigate settings from your listening position without needing to reach for the unit.

The ground loop noise terminator is a physical switch on the back of the unit designed to eliminate audible hum or buzz caused by ground loops in your audio chain. It is particularly useful if you notice background noise when connecting multiple devices to the amplifier.

Absolutely. The A90D functions as a high-quality pre-amplifier, allowing you to connect it to powered monitors or a separate power amplifier. You can easily toggle between headphone and pre-amp modes using the interface.

The R2R relay volume control uses physical relays to switch resistors, ensuring perfect channel balance even at very low volume levels. Unlike traditional potentiometers, it will not develop channel imbalance or scratchy noise over time.

Yes, the redesigned UI includes a volume memorization feature. The device will recall your last used volume level when you power it back on, so you don't have to manually reset it each time.
