I need some help please. I wish to purchase a new digital card and I'm not sure which one is the best for my setup. I was set on buying the Echo Layla, but after reading more on the AW8 it may be the card I need given that I slave to an external tape machine. The Emagic site boasts of AW8 providing continuous sample rate calibration for perfect synchronization, even when using very long audio files. Is this feature alone enough reason to go with this card, or does Layla and others provide the same synchronization accuracy as AW8? Thanks, dm
