Numbers are the manufacturer's stated figures unless marked as measured; sources linked below.
Outputs and power
Not stated: gain, supply voltage, crosstalk.
The SPECIFICATIONS tab lists 'Impedance 32Ω' without saying whether it is the output impedance, the recommended load or the test load (the other rows are all given at 32Ω). The catalog does not use it as output impedance.
THD+N is given as −98 dB(32Ω) with no output level, and separately as THD+N<0.1% at the 122mW@32Ω power figure. The two are different operating points, not a contradiction, but the level for −98 dB is not stated.
Is it enough for your headphones?
NiceHCK rates the NK1 Ultra at 122 mW into 32 Ω. Below is how much of that is left to spare for each kind of headphones when you listen loud, with peaks at 110 dB. A figure marked est. is worked out from that rating.
