Nice system.  
You have a lot more invested in your analog system.  The turntable alone costs about 4 times the streaming source.

  I have never actually heard an Eversolo product but what I have read from users is mixed.  Can you get a loan of a better streamer and then see what you think?

I can guess you wanna spend but imo there is no upside if you think your analog setup is better. keep your analog setup

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.
