KEF LS50 Wireless vs Alternatives

I’ve been using the LS50 W V1 for a few years (after giving up on the thin sounding passive LS50).  I’ve run it with external low end streamers (ifi, Node 2i, Cambridge) to avoid relying on the KEF apps. I’ve tried numerous eq settings to tune it to my room and my SVS sub. Music source is generally streaming through LS50 internal Dac or Schiit Bifrost 2 Dac. 
 

I love the detail and clarity and have tamed the brightness. Low bass is also good as augmented by the sub. The problem for me is that there is a leanness in the lower mids that I can’t fix. My previous systems (all low end but appropriate to my budget) have included Audio Refinement, Musical Fidelity, Creek, Nad and other amps with Thiel PCS, Dyn 140, Fritz etc speakers. These systems all had a fuller upper bass and lower mid region that I find important for listening. This is especially noticeable with good piano recordings. The LS50 is more detailed and the images are more precise than with any of my other attempts, but the voices, instruments etc sound small… with no body. In spite of that, I always return to the clarity of the LS50 W setup. 
 

So I’m considering one more try to find clarity with fullness… on a budget in the used market. I’m  leaning toward Dynaudio Special 40s (I really like the house sound and fullness) with something like a Ragnarok integrated. The other option is the LS50 W ii (maybe the upgraded power and DSP will fill in the sound). 
 

So I’m looking for input from others who have traveled a similar path and found success (or failed). I’d like to keep any discussion focused on my rather narrowly defined issue. I’m not unhappy with the level of audio performance in my very limited price range, and not going to enter the arms race. Just looking to decide whether to stick where I am now or try yet another parallel path. 
 

Thanks in advance for any insights.
