I know that many a VDH Frog has been attached to the JMW arms with excellent results. As Beemer can attest to above. Technically, the Frogs high Static complicance mates very well with the JMW Uni arm. Sonically, this VDH is a middle of the road performer in the line( but better than many high end models from other companies, especially at its price!)..A closed body design that shares some Grasshopper heritage, Its dynamic and open sounding with its tonal balance( or energy)favored toward the highs,yet, not bright in the least!
All said, Raul's advice to hear the combo first would be great in its at all possible, with your system in your room... However, we dont often have the ability to do that, especially in home with a analog front end of that quality and price. The next best, is to hear the combo at the dealers or in a friends set up. But,IMO.. I dont think you would go wrong with this match.
Good luck!
