**1****Evaluating AD/DA loops by means of Audio Diffmaker**

I evaluated the AD-DA loops from Prism Orpheus and Mytek proposed in this post .

by means of Audio DiffMaker and tested also on the same audio sample three audio interfaces : RME Fireface 400, RME Babyface and Steinberg MR816X. Here below the 'correlated null depth' figures (both last ones) from Audio DiifMaker, the higher the figures in dB, the closer to the original the AD-DA loop:

Mytek 8 x 192

-1,002sec, 0,450dB (L), 0,553dB (R)..Corr Depth: 35,3 dB (L), 36,9 dB (R)

Orpheus

-1sec, 0,075dB (L), 0,064dB (R)..Corr Depth: 30,8 dB (L), 32,4 dB (R)

Fireface 400

-36,94usec, 0,298dB (L), 0,311dB (R)..Corr Depth: 30,2 dB (L), 31,8 dB (R)

MR816X

-2,101msec, 1,104dB (L), 0,605dB (R)..Corr Depth: 19,1 dB (L), 21,0 dB (R)

Babyface

1,555usec, 0,352dB (L), 0,414dB (R)..Corr Depth: 9,2 dB (L), 10,8 dB (R)

Results from other AD-DA converters are welcome.
