I recently treated myself with a Sony PCM-D100. The price was just too good.
Here is a quick ADC Line In comparison with my Olympus LS-11. The measurements were done in REW V5.20 RC8b with a Motu M4 using the unbalanced monitor output (Output 1 RCA) which was connected to the Topping L30 so that I didn't have to digitally lower the signal with the Motu and possibly degrade the SNR of the signal. The 1kHz test signals were recorded in 24bit 44.1kHz to the SD cards and the WAV files were later analyzed in REW. For reference also the best case scenario I achieved with the M4 and L30 when looping back the unbalanced RCA output.
Olympus LS-11:
Noise: -88.1 dBFS
Distortion: -82.3 dB
THD+N: -81.3
Sony PCM-D100:
Noise: -96 dBFS
Distortion: -97.7 dB
THD+N: -93 dB
Motu M4 + Topping L30 Loopback:
Noise: -108.5 dBFS
Distortion: -107.7 dB
THD+N: 103 dB
