That sounds awesome. Even on a "normal" headphone amp I find the HE-6 to be fantastic. I'm getting a speaker amp for them as everyone says that's the way you need to drive them... I've always longed for serious bass impact from a headphone and from my research it was the HE-6 or Abyss that get the jaw to drop in that regard. But the Abyss is much higher in price, so I jumped on an HE-6 when I found it. Nevertheless, the technical ability, clarity and aliveness of the HE-6 is outstanding. They brought out emotions in me when listening. In basically every area, they seem to impress, regardless of what you are looking for out of them. What a headphone this is! I wonder why, nearly 10 years later, Hifiman doesn't release a refresh to this masterpiece!
