Hi all, i'm new to this headphones world and just recently buy a SR80i, HD668B, and Topping D2 DAC/Amp. While its sound good but not really to my liking, i can't descript it because i don't really understand the terminology and my bad English but i'll try. What I don't like from combination of D2 with both phones is it's sibilance (?). SR80 also sounds a bit too bright (?) and bass a bit overwhelm by mids. i just post links from YouTube hopping anyone can give a advice based on music genre i like to listen.
