Why do we want to distortions?

like ralph said...

how we hear and how we process good and bad sounds we hear

  CH Precision , the 10 serie , has global and local feedback settings.  Is it related with the feedback , you are talking about ?

Yes.

Thank you for your comments.  but what I am trying to understand is if the original recording is with  euphonic distortions that are deemed as positive then don't we want the most transparent system to hear the original   and   How does tube  euphonic distortions add a stage to the sound?

i believe the recording and mastering processes ’bleach out’ the sound to some degree ... there are losses at each step... therefore the sympathetic distortions in reproduction ’rebuild’ or ’restore’ some of the warmth, body, and dimensionality of the music (even most ’analog’ recordings are digitized, and even analog handling has losses)

like every time you store or handle or freeze food, you lose some of the texture and original ’realness’ of the food... thus ’seasoning’ often make it nice again... different, but nicer than if you didn’t...
