Wondering about Crack and Meze

[Chris]

As of now, I am quite diggin' the Meze 99 Classics...  they are, I think, 32 ohm impedence..  However, they all say how efficient they are.. even an iphone powers them well enough... So, if they are efficient, could a Crack or Crack2 power them?  IOW, an "efficient" 32 ohm versus a tougher headphone like the AKG K712.. my other choice that is NOT good for the Crack?....

There is no issue with power. The problem is the output impedance of the Crack and Crackatwoa are around a couple hundred ohms down to maybe 120 depending upon configuration. For a 32 ohm phone you want an amp with a much lower output impedance.

Ok Thanks Doc..
