Thanks for the information Mac.

Just pushed the same file again, and GW indicated that the levels were: +0.31 and +0.31 dB L/R channels. Again, to my old tired ears, I couldn't detect any Thwack. I'm not going out on a limb to suggest there is no distortion, but in theory, there should be some. But it doesn't seem to be obviously audible.

Mac, do you have any more insight on this? (Yes, I realize I'm a bit off topic).
