(se)Ok. But I haven't seen any evidence that the "improved behavior" is any sort of objective technical improvement. It's been well-established for perhaps a century now that DC on a transformer's primary or secondary increases signal distortion.well established by whom? what has been established is the reduced perm, hence the reduced inductance for a given source increases distortion if you don;t account for the reduction in perm.
(se)Why? That might well be the answer. If you're going to reject that possibility out of hand, then you're obviously more concerned with confirming some preconcieved belief than getting at the truth.
no, it just makes no sense to me.... having too little inductance causing distortion makes sense, and that could explain a pleasing distortion, but discussion of linear perm is much more "pure" and untainted from the numbers that limit an arguement.
i really don't care, like you i enjoy what i like and feel no need to make excuses, and won;t apaologize for what i like, but that doesn;t stop me from trying to figure out why.
(se)That being the case, I think I'll just go back to enjoying listening to music with a bit of DC bias on my transformers and not really care why it sounds better to me.
its this percise belief that made me want to have the discussion with you in the first place.... thanks.
