You’ll find a lot of backlash against the THX amps on this forum, so will get a lot of “no” I expect.
I don’t agree with the backlash necessarily but probably end up agreeing with the “no”. Unless you’re experiencing ground loops and want the “balanced” (in quotes) connection, or unless you have headphones that need more power than the Liquid Spark provides, and you run those balanced, the Liquid Spark will sound as good and provides more power (I believe) than the THX887 does single-ended.
That said, I don’t know the power requirements of the LCD-X offhand; and in terms of bang for buck , you can get more powerful single-ended amps cheaper than the THX887.
On the other hand, if you want the versatility of running headphones out of both single ended and xlr jacks, if you have or expect to get headphones that will require or benefit from running balanced, and if you will get a DAC that you can connect balanced , in think the 887 is a good choice. (And here’s where others will disagree most with me, I expect!).
Especially given your DAC and its lack of a balanced connection, I’d still land mostly on “no” . Full disclosure - I have both the Liquid Spark and the Monolith 887.
