I have been using these headphones for a year now, in love with them, I use them with the Asus Xonar Essence ST soundcard and I have them set on high gain (+12) but I have some questions..
When we amplify headphones, is this mainly to improve the sound quality and reduce the noise floor?
I am advised not to put the headphones on extra high gain by the Asus software, would it be safe to put my headphones on extra high gain for this quality increase and just keep them on a reasonable level?
Would an external headphone amp be better? Could I combine my soundcard amp with this amp too? If so, what good price/cost ratio deals are there which combine well with my HD650s?
Thanks, I hope you are able to enlighten me
