MKiii should be able to get there but it may take some rolling of course. 700's present so much detail and space that, for me, it was just a matter of making sure that they had the warmth to tame the highs and thicken things up a bit. I powered them with a Vali 2 fed by a dragonfly 1.2 which didn't sound great off the bat. Then I rolled in an EH 6CG7 (which is, I believe, getting close to the warmest/tubiest that amp can sound) and it really changed for me. The 700's were always an interesting, revealing and exciting listen but I had usually found them emotionally lacking. The warmer tube actually closed in the space a little bit which seemed to bring a coherence that had been missing. Suddenly I was listening to music instead of lots of little sounds coming at me from every different direction. In the end, for my musical tastes, the mids were a bit too recessed to be my primary cans. I realized that I was often bringing the volume up to fatiguing levels in order to listen to vocals and I got rid of them. Wouldn't mind owning them again though. Some of my jazz and instrumental albums have never sounded better.
