Irler, how large is your music collection? If it is sufficiently large, then further upgrades in your system might well be warranted. If your collection is more modest, then you may be better served in developing your audiophile tendencies by buying $3-5k in music (including live concerts). I say this because you've already assembled a very high quality playback system. Your components are well chosen and complement each other (I'm familiar with everything except your PCs). You would basically have to start from scratch (excepting the EMC-1) and spend significantly more dollars to significantly upgrade the music reproduction capabilities of your system.
You admit that you're a neophyte. Take your time and go slow. It's more enjoyable that way. Good luck!
