I've had the Musical Fidelity M5si, the Creek Evo, and the Sphinx V1. Of the three, I preferred the Musical Fidelity. In my system it had seemingly unlimited power, good detail, and a deep soundstage. The Creek was also nice - a smooth sound, very easy to listen to. I didn't think it brought out low level details as well as the M5si, and it wasn't quite as dynamic as the MF. My Rogue was V1, and it was far too noisy. Haven't heard the V3.
