Great description of your upgrade journey. Excepting the Tera, I have the LPG (Diana Edition), 1Z, 380CU, 240SS (RW Mod), Mojo and Hugo. I do not like the Mojo pairing with cell phone. I think a dedicated dap is better. Your 240SS is very good and is a gem. I actually like it better than the LPG. But the LPG has one thing that no one has in the group that is the power to drive full size can. It is the most powerful dap in the group may be with the exception of Hugo2 that is coming out. Yes the 1Z and the 380cu are at the top of dap at present with the 1Z leading slightly. However, the 380cu has more air and clarity whereas the 1Z is warmer, darker and thicker or lusher as some people will describe it. Some people may like one over the other. As for UI, until I use the 1Z, AK has the best UI, but 1Z give you much more intuitive control over your music.
It's hard to find specs on the LTPG Diana edition. I found this in the LTPG thread:

Joe Skubinski, in this interview at Rocky Mountain Audio Fest 2016 (4 posts above this one) states that the Diana puts an output of "about half a watt into planar magnetic headphones" (specifically indicating that it was customized for the Abyss AB-1266, which is spec-ed at 46 ohms input impedance, 85 dB/mW).
500mW@46 Ohms for the Diana isn't too far off from Mojo/Hugo 600mW@32 Ohm (LTPG is 500mW@32 Ohms). The rest are not as powerful for sure, but I disagree 100% that the Mojo isn't powerful enough to drive full size cans.
