My vote is for Wadia. I recently adjusted the internal DIP switches in my Wadia 850 in order to maximize its output level. Wow, what a difference this made. I am now listening between the 70-90 range comparred to the 45-65 range. Since I am operating the 850 well beyond the top half of its range the resolution and overall weight of the presentation has been incresed dramatically. When comparing the Wadia's w/out a preamp make sure the internal DIP switches are set to match your systems sensitivity.
