So I've been doing a bit of research and am looking for the best sound possible that I can get out of my computer. I currently own a set of Denon ah-D2000 and am thinking of either getting the Sennheiser 650's or 700's. I also have an internal sound card but feel that this isn't adequate enough for producing the best quality sound.
I am thinking of buying:
For headphones (or the 650s) ...reccomendations??
What is the difference?
Is this all I need? Are there any extra cables I should be getting or will this take care of it. Also, is this completely overkill for listening to radio/itunes music? I'm not looking to waste money but definitely want a very quality sound setup.
Thanks in advance!
