I think its going to take a bigger budget to be your LP12 assuming its dialed in.
The Eversolo A6 is actually pretty good on its own. The A8 for about $2k is better and pretty hard to beat without spending multiples of its price.
I dont know what your other electronics are, but you described as "mid-fi." So, perhaps your sonic bottleneck is somewhere else in your setup.
If I were you, I'd look at used perhaps a DAC that sold new for $10k+ that selled today for much less. I propose patience because spending $2j may be at best a sideways move and at worst a step backwards.
