Right now i'm using some unknow thomson headphones for less then 10 $ ;] and I've never used better ones ;D

my question is, right now I have some money which I would like to spend on new headphones...

I'm going to use it mostly with my PlayStation 2 (right now connected with my JVC mx-j850r) playing games :] 2nd use will be listening to music on my PC (SBLive 5.1)

good audio effects in games are the most importent to me... and YES stuff like virtuall surround etc. is much more importent than extra - clear sound ;] (i hope you know what I mean)

i'm thinking about:

akg K66
Sony MDR-if540rk
Panasonic RP-wf930
Panasonic RP-ht711
Sennheiser HD 515
Sennheiser RS120

which (or maybe something else for similar price?? ) should I buy and why ??? Will "normal" stereo sound in 515 be (for me) something more exciting than v. surround systems in panasonic's or sony's ?

please help!

waiting for your answers
marx

ps. are sony mdr-g74sl MUCH better than MDR-g58v or mdr-g54lp ?? I mean is it better to spend this 10 $ more on first or not ?
ps2. sorry but my english is not perfect... ;P
