I do like my Wadia very much, but I keep reading about the latest advances in digital and wonder what I'm missing. A couple years ago, it was Audiomeca, Audio Aero and Electrocompaniet. Now it's EMM and Reimyo. I realize the reviews are a often lot of unwarranted hype, but at some point, I'm going to try something else. I would like a greater sense of air and smoothness, but what I have now is really good. I hate to make trade-offs. When I upgrade, I don't want to give up the bass for something else. I want everyhting I've got, and then some. Not always easy, especially if you are not buying new (and can't use a dealer's showroom).
The other thing about the Wadia is that I've been running without a pre-amp. Now that I'm looking at preamps, I realize they have very distinctive personalities, and so far, it sems like you always lose something, even if you gain something elswe, when you add a preamp.
