Help with future amp connection

Hi guys. i have a question about my future setup.
i post 3 pictures with the different options.
i plan to use a Xlr splitter to connect my dac to 3 amps ( balanced THX 789 and loxjie, unbalanced liquid spark).
So which would be the better solution:

  1. directly through the unbalance out from the dac.
  2. Xlr Balance to Rca ( i know theres no benefit but i like how it looks, also some people says depending on the implementation on the dac the xlr output could be better or the unbalance out could be better.)
  3. This switch ( https://www.amazon.com/gp/product/B07D7P7366/ref=ox_sc_saved_title_1?smid=ADPE7GPX91ORE&psc=1) have 2 xlr and 1 rca inputs to 2 xlr and 1 rca output.

Another question is. how do you connect 2 balanced amp to 1 unbalanced amp. I have seen they use XLR Y splitters. but i think the switch would be better.
