Depends what you're looking for, and where you're headed with your audio system. Vandies are almost universally recognized as great speakers, but aren't the best for heavy metal, etc. They require lots of power, sound best when bi-amped with either high output tube amps or solid state with perhaps a tube pre-amp. Form follows function with Vandies, as they are not breathtakingly beautiful but image like electrostatics when properly set up. I think we're seeing many for sale now that the Quattro is being introduced, so it should be a buyers market. The VR4jr is beautiful to behold and more efficient. I understand that they image better with tube amps than with solid state. With Sim Audio gear, they were slightly boxey, a little sibilant, ever so slightly unresolving at lower volumes, but they rocked on rock music. Note that Vandies are time and phase coherent, and VR4jr's are... well you read the literature and tell me. Neither one would be my first choice, because I can't afford a pair of megawatt tube amps, and I want better imaging than VR4jr.
