Got the Audeze LCD-2 on demo today. The Magni drives them SO WELL. I don't feel the sound is muddy at all. Tried out of the E17 and Little Dot MKIII just to compare and yep, I get a muddy sound out of those. The Magni and Modi works great. The -12dB attenuators I have allow me to get to about 3 o'clock on the pot before it becomes uncomfortable.
