Performance At 24 Bits/96 KHz
Frequency response : You have to work at 96 kHz to cover the audio spectrum up to 20 kHz without any noticeable attenuation. You can get up to around 40 kHz to -0.5 dB, which is very satisfactory.
Noise level : No problem, the sound remains as low on the audio track but is slightly louder on the higher frequencies so the figures are not so good.
Motional capacitance : With the weighting, the result improves in relation to other frequencies because the noise on the audio track is quieter.
Distortion : The result for actual distortion (minus noise) is very good. The two predominant harmonics (H2 and H3) were rejected at over 100 dB and others at more than 120 dB...
Intermodulation : The result remains perfectly satisfactory, as in slightly lower sampling frequencies.
Diaphony : Using diaphonics that are higher than 90 dB, the Platinum ZS remains true to its predecessors, which were excellent in this respect.
