BigH, Thanks a lot,
Yes of course, Let me describe the sound I hear , I think its the room and bad bass :
There is a bad bass (i call it) sounds like GIN GIN that never ends from the begining of the sound till the end, it makes every instruments and vocals to be hollow and hiden back of this sound and i cant focus on any instrument or the singer and is very unpleasent. I think that is the couse of problem.
sounds can not seperate from each other and that Gin Gin is always in my ear.
I feel that everything is ok but this bad bass destroys the music...!!!
I really appreciate your help.
