“Measure better” doesn’t always mean “sound better”. I might add the Zen Can to the Zen Dac though to really make those Hifiman Headphones shine though. The Zen line is warmer than the Topping or Schiit offerings and personally speaking I think that works well with the Sundaras. I compared it to the JDS Labs Atom Amp for example, which is a much more “neutral” amp closer to the Topping or Schiit ones (people say the Heresy sounds identical) and I found that distortion could get a little harsh on the Sundaras.
