I tried out the LCD-2 (2016) and LCD-X for a couple hours and ended up getting the LCD-2 because at the time I felt the LCD-X wasn’t worth the much higher cost. I thought the LCD-X was more musical, more close in, with exciting treble. I thought the LCD-2 was more dynamic and had enough of the detail I wanted.
I might get a second hand LCD-X in future to compare - it’s much nicer to compare gear at home.
At home I think the LCD-2 sounds excellent in many ways but maybe a bit soft and distant. Slightly odd signature. It could just be I need more time with them - which I will.
What are your thoughts?
