Ribbon/cone hybrids often polarize opinion. I don't know the VMPS, but I love (and still own) the original Red Rose mini monitor with the "roof mounted" ribbon. Strictly speaking, this isn't the most neutral system out there, but it produces beautiful extended bandwith sound from a small box. IMHO, ribbons and cones can play nicely together but the result may not be for every taste.
Good Luck
