Would wiring Ever solo A6 Master directly to EcoFlow DC output offer any advantages?

Thank you all following up with me here, what I have been experienced with EcoFlow DC output: 

After plugging my AT&T modem, fiber converter, and Wi-Fi router directly into the EcoFlow battery’s DC outputs (it has a total of three), I noticed a significant improvement in sound quality — clearer and more focused than what I experienced using a linear power supply. This improvement got me thinking: perhaps wiring DC power directly from the EcoFlow to my Eversolo A6 could yield similar benefits.

No advantage to be gained

I would be worried about correct voltage.
Also, if this was a thing, someone would’ve done it a long time ago. The only guy doing something similar to that is Stromtank https://stromtank.com/ . Pretty sure most of us don’t have the scratch for these guys.
