Short answer: the Schiit Magni Unity with Mesh DAC. It ranks #19 of 43 DAC and headphone amp combos by measured performance, rated 4.4/5, at $239. The Fosi Audio K7 ranks #26, rated 4.1/5, at $199.99, $39.01 cheaper, not enough of a saving to outweigh the sound-quality gap.
The Schiit Magni Unity with Mesh DAC is the better-sounding option. Audio Science Review measured a SINAD of 109 dB with the Mesh DAC fitted, clean enough that noise and distortion stay out of the way for nearly all listening. Watch for: There are no balanced outputs and the only digital input is USB-C, with no optical, coaxial or Bluetooth.
What the Fosi Audio K7 does well: Audio Science Review measured a SINAD of 116 dB, so its noise and distortion are inaudible. Watch for: Fosi Audio doesn’t publish a 32 ohm power figure, so its headroom for hard to drive headphones is unclear.
Buy the Schiit Magni Unity with Mesh DAC. It is rated higher, and saving $39.01 with the Fosi Audio K7 does not make up for the sound-quality gap.

Schiit Magni Unity with Mesh DAC: $239.00 Amazon eBay
Pros: Audio Science Review measured a SINAD of 109 dB with the Mesh DAC fitted, clean enough that noise and distortion stay out of the way for nearly all listening. Schiit rates it at 2.5 W into 32 ohms and 415 mW into 300 ohms, enough for power hungry planar magnetic and high impedance headphones, and its RCA preamp outputs can also feed powered speakers.
Cons: There are no balanced outputs and the only digital input is USB-C, with no optical, coaxial or Bluetooth. The Topping DX3 Pro+ rates higher for less and adds those extra inputs.

Fosi Audio K7: $199.99 Amazon eBay
Pros: Audio Science Review measured a SINAD of 116 dB, so its noise and distortion are inaudible. It is unusually flexible for the money, with USB, optical, coaxial and Bluetooth inputs (SBC, aptX HD, aptX LL), RCA line out, a 4.4 mm balanced headphone jack, a microphone input and bass and treble knobs.
Cons: Fosi Audio doesn’t publish a 32 ohm power figure, so its headroom for hard to drive headphones is unclear. The SMSL DS20 rates higher for a little less, and the Fosi Audio SK02 rates slightly higher for much less. Its Bluetooth lacks AAC and LDAC.
