thanks for the great informative comparisons! I am still not sure about the Offramp 5 for my A-Gd M7 but the temptation is very strong :)
Have you compared the direct USB connection of the M7 (with the latest drivers and firmware 2014V2) and the Off5>I2S>M7?
What cable do you use for the i2S connection Off5>M7?
Many thanks in advance!
