Anybody use an audiophile hearing aids?

Wow! I'm audiophile and musician too.
I saw a couple WIDEX Dream 440 on the internet with different letters and numbers  like this one  WIDEX DREAM 440 D4-FA,
I think they are discontinued already, but I found a dealer in Germany and they still have them brand new.

Widex Dream D9 440 saw this model too, do you know the difference?

All I know is my model is Windex 440 - do not know anything about D9 or anything else, - sorry.  If it is discontinued I do not know, but regardless you cannot go wrong with ANY of the Widex models in my opinion - new ones would probably be better.  I had an older model from 2006 that was great - for music - it just finally wore out in 2014 - probably from overuse.  it just broke apart.  I do not think you can get more that 8 to 10 years out of any model hearing aid by any firm.  The technology improves and they just don't last forever.
