DAC upgrade

I went from a Rockna Wavedream to a Lector s192 tube based dac. Couldn’t be further apart as far as comparing quality dacs are concerned. Rockna is super accurate with a strong attack. Saw deep into the recordings. Very real sounding. The Lector is very smooth and liquid. Connect with the music differently with both. With the Lector I just listen. The Rockna I tended to analyze the music more. Perhaps not quite as relaxing for me personally. I wouldn’t say that’s a negative for the Rockna and I would gladly own one again. I was selling equipment and was able to swap dacs and took the opportunity. I got to hear my system with each dac prior to having to decide. Wish I could own both. 
‘I’ve owned the Topping dl90, Cambridge cxn modified by ModWright with tubes and Audio Note dacs as well. The Rockna and Lector are at another level. The AN was unique and enjoyable as well. Good luck

Thank you all so much. 
as for interconnects, have Bordost Odin 2 for power cords to the M400 amps, Audioquest Dragon to streamer and preamp, Valhalla 2 to DAVE, Odin 1 xlr preamp to amps, Siltech between DAC and preamp, Valhalla 2 Ethernet with Nordost qnet with fiber interposed and Valhalla 2 bnc streamer to DAC. 

+1 on the Audio Mirror DACs.  Just recently acquired the Tubadour VI and it's sublime!  I look forward to it breaking in and sounding even better.  Very natural and musical DAC.  I would seriously consider contacting Vlad as he's the sweetest guy you'll ever come across.  I can only imagine how his flagship Wave DAC sounds.  It's within your budget and there's one at a steal of a used price on USAM now.  

Take a look into Vitus DACs, which are known for sounding warm. Might be a great match for your system. I own the Masterpiece DAC and am very happy. 

That system is tuned for ultimate resolution with all the Nordost and AQ Dragons. New DAC in $20k - $25k range should be a definite improvement over the DAVE. Get a new DAC and may be as a next step revisit your cabling to mix in some warmer sounding interconnects or speaker cables.
