branded player dun have much sound difference with the player themself...unless u connect them to their processor which support a lot more tuning features, then it make the difference. btw, both player are not in same price range...so it's a bit hard to compare

520 use h100 is just waste of money la....to me la....

if u wan to add in processor, get pioneer or alpine..if not, any branded mm hu sound identical....nothing much difference. by getting mm hu, normally consider the features first...cos it's a mm hu.
