Interesting.
In my limited listening with the M-path (Only a few hours), I have found just the opposite. The Gede, being silver, and heavily shielded makes for a very detailed system. Especially in the treble region. In fact, it is more detailed, and "treble-enhancing" than my Grover Silver Reference. As for the M-Path; I find it quite bright. However, the sound-staging is excellent. It seems to enhance the air around instruments. It does seem to bring treble forward though. The treble is smooth however. The m-path has better bass than the Gede, but is not as detailed. I am going to give the m-path alot more listening. I am quite intrigued by it. More details later.

***EDIT***
Simply put:
Gede: Detailed, smooth treble, decent bass, slightly thin midrange.
M-Path: Bright, forward decently detailed treble, good bass, "fat" midrange, lots of air.
