Hey, I'm a new guy here. I'm looking for a headphones mainly for music and movies. Budget is around RM600 and I don't have an amp. Am currently looking at Sony MDR-7506/V6, Sennheiser HD 448, HD 555 and HD 595. Any advice on that? And do you have MDR-7506 in stock? It's like kinda hard to find. My friend manage to find them in Singapore but they sell at SGD250, which I think is quite expensive when compared to how much the sell in US. And can you PM me the price of the headphones mentioned here and your suggestions as well? Thank you very much.

Would you say that Denon AH-D1001 is a huge upgrade from Sennheiser PX100?
