Tested by recording a test sequence from a Lindos MS20 using the Fourtrack app and an iPhone 3Gs. The recording (unmixed) was played back to the MS20 using Adobe Audition and a Yellow TEC PUC2 A/D D/A.
True distortion value at +15dB is -30dB wtd (relative) and -20 dB wtd (rel) at +18. I.e fails grade B on distortion at +18. This is a shame as in all other respects this is a good A/D. Input circuits are probably clipping. Seems fine at +12. Dynamic range is more like 90dB (not 96 as quoted in their specifications)

Note that using the Mixdown function in Fourtrack seems to modify the audio even when effects and compression are turned off. Download the tracks seperately to aviod this.
