I owned a Wadia player for almost 2 years. For the first year I used only the volume control and was convinced no preamp was needed. After all how can adding another piece be better than using the source itself? Then I added a nice preamp. To this day that addition was the single most impact any gear change has ever made in my system. You are simply holding the rest of your gear back by avoiding a preamp.
As to the rest of your question I've been using Vac gear on Harbeth Super HL-5's and they sound absolutely marvelous together.
