You are getting contradictory information from different sources approaching the problem from different angles.
Start with speakers and their placement. You have a lifetime thereafter to audition various streamers, DACs, preamps, amps, and cables/ICs. Your question is like an equation requiring a constant. Let the speakers and their placement be the constant. Every component prior in the chain is a variable which you can spend forever tweaking to your preference. Or think of it as building a house. Speakers & their placement are the foundation; finish carpentry might be DAC X vs DAC Y vs. DAC Z, which is where I have landed after 10 years.
