I really like my system, but am kind of getting an itch to get something different. So, given what I have for a pre, amp and DAC, what should I upgrade that will probably give me an appreciable improvement?
If you really like your system, perhaps you can just enjoy the music and not tinker with it - human beings have this psychological need to venture out and experience something new, and this can get costly in hifi real fast. You know about the law of diminishing returns - higher you go, the less satisfying will be your returns, unless you spend much much more... 06-03-13: Liquid-smooth
I'd say listen to Liquid-smooth. I agree, if you like your system, enjoy it. When you begin to tinker there are no guarantees of anything except that you'll be spending money. I've observed that upgraditis often occurs because of dissatisfaction with the system. You really like yours; be happy for a time.
