Sadly I never got a chance to try dual vidars which I believe sound different. For single vidar I'm having around, I think it the most honest and arguably the most accurate among the bunch, but doesn't have rich timbre, shimmering sparkles, and airiness (I think I like overly and colorfully done in these aspects). It's not that boring by any means though. Just relatively so. Indeed JLH did better than Vidar here although Vidar technically superior.
