I still use mine directly connected to my computer along with a set of original LCD-2s. I really like the combo and while I have been on the verge of jumping on a tube amp and newer headphones, listening to good music on what I already have has stopped me from spending the money.

  +1 on the Steely Dan "Aja".  The mastering on that album was well done.  I'll have to look into the Tom Petty album as well.  I'm a fan, but don't happen to have "Damn the Torpedoes."  

  I picked up the digital remaster of DSOTM based on recommendations in this thread and I find it more impressive than the original release of The Wall.  I don't have have a remastered copy of The Wall for an apples-to-apples comparison, though.

I agree completely with superjawes.  When I first decided to improve my headphones, I had a department store model of Koss cans that I was not satisfied with.  I bought the Grado sr80i which improved my listening experience immensely.  Most recently, I upgraded from those to the Audeze LCD-2r2...

+1 to making your own.  I wish I had researched that option prior to purchasing a replacement for my stock LCD-2 cable.
