Outputs and power
Not stated: gain, supply voltage.
Linsoul prints SNR ≥ 114 dB (32Ω load, A-weighted); kiwiears.com lists no SNR. The <0.004%, <3 µV, ±0.2 dB and ≥114 dB lines are word for word the Allegro Mini's figures, so they may be a shared template rather than AD1 measurements.
Both pages give THD+N −85 dB (1 kHz, 0 dBFS, typ.; about 0.0056%) and <0.004% (32 Ω, A-weighted). Different conditions, so not strictly contradictory; both are shown.
The device
From Kiwi Ears's product page unless markedLinsoul names the chip KT02H20; kiwiears.com says only "Integrated DAC", and the Kiwi Ears web equalizer labels the device "KT-0211L AD1" (a KT Micro device label there, not a chip claim). Catalog shows KT02H20 as stated by Linsoul.
