Can't comment on the LCD-X since I haven't heard them. But I completely agree with your assessment of the T1s. I owned them, spent money on a balanced cable for them, and then sold them soon afterwards. Not enough bass, too sharp in the upper mids/treble. I found them almost painful to listen to.
For me, the 560s have a fairly unique sound sig. V-shaped, planar bass, very open soundstage. I find myself pulling them out as an alternative to my Auteur/Utopia faves -- more frequently than my HEKv2.
So the question is, are you trying to find another set of cans with similar characteristics, but just 'better'? Or are you looking for something a little (or a lot) different?
Similar characteristics just "better". As much as I loved the 560s sound I couldn't help but think that they wouldn't hold up too well over time due to HIFIMAN's reputation in terms of quality. When it comes to audio equipment I aim to upgrade over my previous set. I got the T1 gen 2's because I thought it was time to upgrade to a TOTL headphone from a company that I can trust to make a long lasting headphone, the reviews gave the impression that it was musical too. Just found the sound signature not to my liking like the 560s which are close to my ideal type of sound.
