Yeah sure,from your preferences and what you are describing that would be really tough to pick one. I had fun building my 1TDX's and they really are great speakers. They don't measure as well as the LX or M105 but in room they perform well. The LX's can come across as plain sometimes too,I'm not sure what it is,they are very neutral. The 1TDX's had more presence in the 4khz-8khz going off of measurements at my mlp,but never sounded bright to me. I enjoy both for music. If I had to pick between those two for music only I might pick the 1TDX but mainly for sentimental reasons since I built mine. The LX is objectively the better speaker.
