Hey there - I'm thinking of the exact same combo at the mo - how are you finding it now?   I have the DT-880 250 Ohms, and am upgrading to the 600 ohms (I heard they have better smoother highs as I'm finding the highs on the 250s a little harsh.  How are the lows on the 600s with the E09K?

So?  Any sign of that review? ;)   Was looking to pick this up to drive a pair of DT-880s (600 Ohm) - would it be up to the job of driving a 600 Ohm pair?   Thanks! Phil
