The Topping DX9 Discrete is a fully balanced DAC and headphone amp that uses a discrete converter instead of a packaged DAC chip, with an XU-316 USB interface and support for DSD512 and 32-bit/768kHz. Its ten-band onboard PEQ suits owners of demanding headphones who want correction curves that follow them across sources.
Who the Topping DX9 Discrete is for
EQ tinkerers: The ten-band parametric EQ runs in the device itself, so headphone correction curves follow you across sources instead of living in one computer's software.
Owners of demanding headphones: Its fully balanced topology makes it a flagship-tier desk unit for demanding headphones and listeners unwilling to compromise on the source.
Hi-res collectors: It handles DSD512 and 32-bit/768kHz, with an XU-316 USB interface.
Discrete-design fans: Conversion comes from a discrete design rather than a packaged DAC chip.
Skip it if: you want a stepping-stone upgrade; the DX9 Discrete is pitched as an end-of-chain desk unit.

Topping DX9 Discrete vs similar options
vs FiiO K17: Uses AK4191EQ + dual AK4499EX chips instead of a discrete converter, with a 4000mW + 4000mW balanced Class AB stage and a 31-band PEQ vs ten-band; pick the DX9 Discrete for discrete conversion.
vs FiiO K19: FiiO's flagship all-in-one with a dual-DAC architecture, one converter per channel, and Hi-Res Audio certification; pick the DX9 Discrete for a discrete converter design rather than packaged DAC chips.
vs Shanling EM7: An all-in-one desktop music player on an ES9038Pro chip with a built-in headphone amp and Bluetooth 5.0, replacing streamer, DAC and amp; pick the DX9 Discrete if you already have a source.
