Mostly it's not a problem with SETs, it happens naturally as they tend to be simple in nature using a lot of grounded cathode based designs at each stage. In a multi-tube non-inverting stage you could look at the collective output but it's harder to predict what is happening.In a three stage SET the first stage adds to the third. So for instance if you made the first stage extremely linear, the cancellation that you could engineer between the driver and OP stages would not be greatly affected since the first stage distortion is comparatively small.
