The HD555 and the HD595 are so close that it hardly is worth the price you'd pay for the HD595. The Extra money the OP didn't spend should go towards a nice receiver and a good little amp. This is sorta the reason why no one was saying the HD650 or the K701's cause without a nice amp it would sound muddy and it would sound worse then just an HD555 at stock.
ok. but what the cheapest and best for money setup is the best way to go? if i want want watch movies on my laptop. i like to watch action and triller movies. so there need for deep and tight bass wide soundstage and etc..
