New guy here so I should probably apologize for the newb post. I have a ton of reading to do around here. I am looking into headphone audio and the HD800s caught my attention. I've been a regular on AVS for a while under the same handle so I am not a complete newb to audio. I also tend to think that I have a good idea of what good sound reproduction is. I've read a few reviews on the HD800s and am very intrigued by them. I tend to enjoy a detailed and crisp sound presentation. I guess some would call it forward... My question is if going straight to the HD800 is like going to say a B&W Diamond, KEF Reference, etc. in the speaker world? Is such a comparison even possible? How much do the other components in the chain make a difference in headphone audio? I currently use my PC as my 2.1 channel system. I am running the Asus Essence STX. I understand the STX has a pretty good headphone amp. However, is it good enough for the HD800s? If not, can you guys recommend a good headphone amp? I've been looking at Woo Audio but not sure which model would be a good fit. The last question is if it is possible to audition the headphones locally? I am in socal, Orange County area. I've only been able to find only retailers. Thanks.
