The Classics V6 provide a lush sound overall compared to the Vivid which I find lean towards a brighter and more detailed treble. The biggest difference I found was how analogue sounding the V6 Classics are, providing a bit more mid bass and warmth with a sweeter and less brighter treble. Using a pair in the IV stage in the Burson Conductor 3xp with the Vivid duals in the LP stage.
