What would be your source(s) for headphone listening? When you say it will be separate, do you mean that the headphone rig will have its own dedicated source(s) or will use the same sources as listed above?
Your thinking is sound - a decent headphone setup will take you farther down the road of "audiophile" listening for considerably less money than chasing other incremental upgrades elsewhere in your system. The HD600s paired with any number of dedicated headphone amps will yield huge dividends in listening pleasure. Spend some time on www.headfi.org. My experience with the 600s is all positive - great sound and very comfortable. The HD580s are very near the same performance for a little less.
FWIW - keep the NAD and KEF gear. Really good values! I assume that the Technics is sound (is it a 1200?) and the cartridge is an m97xe - there is room for improvement with your phono pre without too much of an additional expenditure. Search www.audioasylum.com (vinyl) for recommendations.
Depending on how much you listen to digital, there are many different directions to go (standalone player, DAC, server) - but suffice to say that there is better than a Sony PlayStation for not alot of moolah.
Good luck and happy listening!
