The key aspect of this solution is the processing of both DSD and PCM streams. Vector Step Resistance Network technology is specially used for decoding DSD, while the traditional R2R scheme is used for processing PCM. The process is controlled by a CPLD chip, which guarantees accurate decoding of musical material.

Topping A900, which not only provides high output power, reaching 22 W for each channel at 16 ohms, but also stands out for its record-breaking dynamic range, signal-to-noise ratio and THD+N distortion factor. The Topping A900 headphone amplifier implements a six-channel fully differential balanced T’ang-ku-la architecture. Thanks to a fully balanced volume control system on electromagnetic relays, the amplifier allows you to accurately control the volume level, keeping distortion at a minimum.

The Topping DX9 Discrete headphone amplifier DAC is equipped with a fully balanced hybrid relay volume control, providing ultra-precise level setting with minimal signal degradation. The correct channel balance is maintained at any volume level, which allows you to work equally well with highly sensitive in-ear headphones, and with low-sensitivity/high-resistance full-size models.

The combination of a fully balanced architecture, high power output, and ultra-low distortion is uncommon in this price segment. Complementing the picture is a convenient trigger control, which allows you to effortlessly integrate the novelty into existing audio systems.

The DAC is based on the AKM AK4497S chip from Asahi Kasei, and the USB interface is implemented on the XMOS XU316 processor, designed to provide fast processing and high stability of translation.
