Do you already have a pair of amp? Headphones that price range are better off with a good pair of amplifier for its full potential.

Actually he can easily grab HD600 + Secret Amp combo, straight from Walabies/yuheng dy.
If he can topup to RM2.3k around there, HD650 not impossible.
Oh wait, forgot to ask. What soundcard/source are you (sieg_wahrheit) using at the moment there?

Yup. Well, what songs do you listen to though? Hmmm.. Some seniors here may be able to give more appropriate suggestions based on your listening types.
Wa. In Japan ah? Studying? When coming back wor?
ESI Maya44 should serve well enough as a DAC I guess. Just hook on an amp. Hmmm..

Hmmm.. Rock and metal eh..
I have a suggestion. You could set back your budget to RM1k first. Tweak out your setup to have your preferred type of source with an Alessandro MS-1.  The Secret Amp is really an amp you can hardly go wrong with (paired it up with MS-1, most of Philips' full sized can ranges, HD580 -> HD650, KSC75, some Mylar IEMs and some earbuds).
If you really want to spend big money on this, I would highly recommend you to go around, listen, audit then only think if your RM2000 is worth investing in whatever is mentioned. Heeey, enjoy life, right?

Hmmmmm.. Can I ask you to help me buy something from Japan? Pleaaasee? *makes cute looking pleading face* Ahahahahahaha.

Ahem Ahem

if you are in Japan, I suggest you go Japan's Hobby street call Akihabara to immerse yourself in Japan's famous audio brand like Audio Technica, Stax, Sony and much more

haha How was it ?

Did you test any Headphones ?

sieg_wahrheit, since u've went to Yodobashi Akiba, would recommend u check out BicCamera shops for further auditions.
Yodobashi is too noisy to my liking to test out the phones and it's kinda hard to do judgement because u cant try with ur own source.

higher end Audio Technicas are worthwhile to test out, like AD2000, A2000X etc, or maybe wooden cans.

once u've aimed certain model, try to check it on Amazon.co.jp, I noticed their price is usually lower than those dept stores.

P/S: high 5 for LYN member in Tokyo!
