The JIEZI FAQ table labels '≥115 dB (32Ω A A-weighted)' as Signal-to-Noise Ratio; the JA11 FAQ table prints the same '≥115 dB（32Ω A-weighted）' in a row labelled 'Noise floor'. A value in dB with ≥ reads as SNR, so the catalog shows it as SNR and states no noise floor.

Is it enough for your headphones?

FiiO rates the JA11 at 30 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.
