I bought a pair of k701s, didnt like them, so returned them. now i am conseidering buying a pair of ms2, but i thougth, that if i save up, i could ge the AD-MD5000, and then a dac and amp. but i intend to spend around £500 or a bit more/less depending on what i save up to. after that, i am set, as i have to save up for a laptop. so, after i spend around £500 thats it for me for the next 3 or 4 years (ie until end of uni). thats the plan anyway.. i might have to block head fi from my computer to save my wallet.
