Take a look into www.head-fi.com. There are sections broken down into headphones and amps. I personaly love the Headroom maxed out reference and I know people who swear by tubes use it to. I also use either Etymotic ER-4S at work and or Senheisser HD-600 at home (ety's are 98% used most). I use a CD-3400/Theta Cobalt or Chroma for front end. Headphone listening is all these people really get into. Good luck and happy listening (w/o the wife).
P.S. my system cost about $1500 (amp new-hard to find used) but I do most of my listening on it being at work alot.
