Sigh. That's exactly what I feared. I acknowledge it's a fine line between too subtle and overblown, but not sure why we should be thankful for "barely noticeable" differences.
The differences will no doubt be more noticable in ideal listening conditions, but I am hoping that the jumps won't be too great. The relatively few times I have felt I might like a different tonal flavour with what I am listening to, the wish has been for only a slight change.
