In Oppo 105 I use RCA outs, and because that on picture were two empty dip 8 slots, for balanced outs…I think V6 Classic model (used 3 pcs dual) is better for Sabre 9018 Dac, than Vivid, which sounds little more detailed than Classic, but Classic gives sound some warm note… Finally impression depends on personal taste… For me, Vivid is better when I use them for monitoring in sound editing process for dialogue, effects, etc
