so I am not an audiophile, I own HD650 which are my first real good headphones.
however I found that there are details I cannot hear unless I pump the volume slightly on the high side.
I dont enjoy loud volume music\ movies, in fact I find it annoying, however I like the level of details I get when the volume on the high side.
it might be worth mentioning that I dont use an AMP, and drive my headphones from PC directly
as far as I know, an amp will allow higher volume ceiling with less distortion, but as I mentioned earlier I dont like high volumes.
let me know your thoughts guys
