I’ve tried a few and the ones that sound most non fatiguing and natural to my ears are the Audio Mirror Toubadour V and the Merason DAC1 latest version. I use both one in my main system and one in my office system. Speakers are Dali Epicon 8 and Focal Diablo Utopia. Amps are pathos adrenalin and kinki B7 monoblocks. streamers are Lumin U2 and Hifi Rose 130. I’ve also tried them out with Sophia electric Set amps and gold note 1175 amp.
I tried the Dave but ultimately didn’t go for it. Also have a Schitt Yggdrasil OG and Okto Dac8 as cheaper alternatives but the AM Toubadour and merason blow them out of the water.
