Yes - I own a pair. I've used them with my 4-board Beta 22, 3-board Beta 22, and HeadAmp GS-X. Sources are Marantz SA-7S1, Sony 5400ES, Bel Canto DAC2.5, Benchmark DAC1.
The LCD-2 aren't horrible, but they are the worst headphones that I own. Inferior in detail resolution and soundstage. Particularly bad for acoustic and orchestral music. I would recommend the HE-6, T1, or a good Stax (SR-507, SR-007, SR-009) as much better alternatives.
I am going to have to disagree as well. I think the LCD-2 are absolutely phenomenal in detail resolution, greater than or equal to the HE-6 or T1. In addition, they have a fantastic midrange and unrivaled bass. I think the soundstage is true to the recording unlike certain headphones like the HD-800. I listen to a lot of music on my speakers and it amazes me how accurately the LCD-2 depicts the soundstage.
They may not be the best at imaging but we're splitting hairs here at this level.
The Stax headphones haven't really really impressed me but I haven't owned a pair so I can't comment. To me, the only headphones that I thought were a notch above the LCD-2 was the R10 and Qualia.
