I have had the MkII for about two years. I was using a Wadia 15 before it and while the Wadia had more punch, the Neko is far superior for musicality, tone and low level harmonic and dynamic contrast. Shunyata power cable and still points took it up quite a bit.
Thinking of upgrading (typical audiophile) so I got on this thread to see what others are saying and possibly moving to.
