Actually, I agree with you. They do sound pretty decent with the Jot with some recordings -- I had forgotten about that. I don't use my Jot with the T1.2 because the Lyr 3 sounds even better, but as others have pointed out, I'm sure there are many solid state amps that do sound quite good with the T1.2. The Jot was the best sounding solid state amp I tried with the T1.2.
I don't recommend the THX 789, and by extension probably wouldn't recommend the THX 888 (though I haven't heard this pairing) with the T1.2. My DAC source when using the THX 789 was an SMSL SU-8, so certainly that could also just have been a bad match.
Bear in mind that I am only speaking from limited experience -- my solid state collection has included the Jot, the THX 789, an Audeze Deckard, Burson Conductor SL 1793, and iFi Micro iDSD Black.
