I have Vandy 3A Sigs. Would never think to call the tweeter sibilant, but I suppose there's plenty of room for subjectivity in that call.
I find the treble and especially midrange detail to be fantastic. I drive mine with an Ayre V5xe, as part of all Ayre stack. The Ayre is 300w / channel into 4 ohms and I would put the minimum power the Vandy 3A needs in that ballpark. My biggest reservation in recommending the Vandies to you is that your amp might not have enough juice. Can you bring your amp to a Vandy dealer to demo?
