Vaipe-
I owned a 390s. Eventually I found a Wadia I liked better that also had volume control. Then I finally took the plunge and bought an Ayre K-1xe preamp to compliment my Ayre amp. Wow was I blown away by the sonic improvement. To this day it was the single biggest improvement I ever made. Everything got clearer and more defined. The soundstage widened more than I thought possible, and the dimensionality went from what I thought was 3-D to what really is 3-D (AKA more refined). I've since come to believe the preamp is the single most important component after speakers.
The Dartzeel is an excellent amp but you're still missing a very important ingredient. Adding a better amp is an inferior upgrade choice IMHO.
Heck don't take my word for it. Seek out a good deal on a used preamp and try it. If you decide I'm full of it resell it and upgrade your amp.
