@julesg13th I didn’t mean bad with my comment and I hope you take time to watch the video. But yes I’d say go demo the speakers or if you can get the speakers in your space even for a fee to demo, that is the ideal thing.
Also get the speakers in your space before doing any treatment. Treatment needs to be targeted and to be targeted a speaker must couple with your room first
Regardless I'm happy you're going about this the correct way making sure you getting the room to fit the speaker as those the biggest factors as to how you're hearing them.
Amp, DAC and every other tinkering that will be done won't come close to the effect of good speaker/room coupling and placement correctness
