I purchased a used ( but in Mint condition ) he-400 (rev4) yesterday. I really like transparency , clarity and its fast sound. He-400 has less bass ( both quality and quantity IMO) and overally less body than my Sig pro but I can live with that but i'm really in trouble with its trebles. I listened all style of Music form Infected Mushroom to Schubert and besides some jazz and some EDM I really can't live with these trebles . With he-400, my favourite Schubert piece (String quintet op 163) makes me grind my teeth.
I need feedback from you experiences he-400 fans :) . Is there any chance trebles will tame with more burn in or should I accept he-400 is not for my tastes ? The first owner and me had about 25h of listening until now .
Thanks for your answers
