Well, I think those who listens vinyl usually are not worried about the lowest distortion, Iam a digital guy and also arent worried with low DHT.
IMO less distortion doesnt mean better sound as currently the distortion of these so-called hi-fi cartridges are already low and the variables in a vinyl system are many.
I cant say which adjusting system I could choose without listening to all the options, however due to the finitude inherent in this format I think vinyl wear is more important than a bit lower distortion, so I could choose the setting that would offers the least wear.
