I owned a Merason Reuss and it was very musical, but also on the warm side. I replaced it with a Bricasti and it added more life to the system. You might try another DAC to see if it opens things up a bit. Nothing against the Merason at all, it is a great unit, I had it coupled with warmer speakers and it was too much.
I don’t know how good the Eversolo is, there is likely room for improvement, but I would start with the DAC.
