Recording in 24 bits at a sampling rate of 48 kHz means moving into a professional mode where we can hope for performance that's clearly beyond the capabilities of consumer products. The results here depend to some degree on the adjustments used during the test: you can favor signal-to-noise ratio or distortion. In the first case, distortion increases a little, and in the second signal-to-noise ratio diminishes slightly. The results we show here are based on optimization of SNR:
- Frequency response (20 Hz - 20 kHz) : +0.02, -0.28 dB
- Weighted SNR : 103.2 dB(A)
- Distortion : 0.011%
- Stereo separation : 103.8 dB
Frequency response :Frequency response is nearly identical to what we got at 44 kHz - that is, excellent - but even slightly better.
Noise level : Noise was very low and didn't increase in the treble, which is very positive.
Dynamic capacity : In 24 bits, dynamic capacity made a leap forward and was really very good.
Distortion : Since we had optimized the signal-to-noise ratio, THD was a little high (for this class of equipment!) but still far from being audible.
Intermodulation : Two zeros after the decimal point - a very good result
Stereo separation : As the results at 44 kHz suggested, stereo crosstalk was practically nil. No comment necessary!
