Welcome guys! I've always loved reading some of the posts on here but now I have my own question. I am in need of a new pair of full size headphones for my pc. I went from a 5.1 setup to nuforce ne700x IEM's. They sound great but are annoying for constant pc use. I can't use speakers because the walls are very thin... I watch movies, tv, and play some games but I don't want a gaming headset or mic. I have always loved sennheiser products but I'm open to anything. I would like to spend under $200 and will probably get an amp/dac in the future. Right now, I can get a pair of HD558 sennheisers for $145 new, which is a great deal from what I've found. That's from a friend of a friend at a store I definitely want wired because I have always felt that the extra money going into the wireless takes away from the quality of the sound. Unless of course you purchase a $400 set or something. Right now in my pc I have an asus xonar dx audio card that has an output impedance of ~100 ohms which is pretty high for headphones, but the dac is very good in it. Should I keep this and just get an amp or get a seperate dac/amp and just use the onboard sound from my mobo? That's another problem all together. Both support spdif. I'm just starting with the headphones right now since i'm not loaded. Any and all help is appreciated!
