The reason I decided on this Schiit stack was that I went to Can Jam in SF, and tried my V700's on several amps, and compared them to other headphones on the same amps. Mine sounded best on the Modi/Magni combo. I tried two other pairs on the combo, one I can't recall, but it was terrible. The other was the HD 680's, which I didn't like at all. They had the soundstage I was getting with the V700's, but they were so bright and tinny on the top end, I couldn't stand listening to them. But that's just my ears.
Before I invested in the Schiit stack, I had a Yamaha C-65, and it had a very warm sound in comparison, but its upper end was not as clear. It could just be due to age--I had planned on refreshing it until it fried one channel. Maybe someday, but in the meantime, loving the Magni 3.
