I have had a PrimaLuna Dialogue Premium Pre for a little over a year now... I have had no problems or issues with it... I love it... It fronts for a McIntosh SS amp driving MartinLogan ESLs... It makes beautiful music... I have no experience with the VTL but it looks like a totally different kind of design with less tubes and a few more "bells and whistles"... Good luck in your decision...
