does it mean the sound produce is very good, even u play it at high volume, your ears stil can accept it...

i having a problem with my Alessandro MS1..  at certain volume, sometime i can hera a very pin-sharp kind of sound.. it's really irritating.. but looking to my current volume, it is stil not high..

bcoz i can hear at loud volume when i use my friend Monster Beat Studio..

dat y i looking for an amp or dac to settle this prob...
