1) which IEM is the best that i can get which have the price around the price of klipsch s4? or is the klipsch s4 is the best around that price range?

2) whats the difference between DAC n AMP? sorry,im quite noob...i always confude between that two

3) so which DAC/AMP is best suited for my senn hd558? with budget less than 350

4) are monster beat cans quality worth the price? heard from my friend that it is not worth the price
