i concur with the suggestion to try an m scaler in front of your dave, it is an obvious thing to do ... the scaler typical adds a sense of richness and relaxedness to the sound of the chord dac it is connected to
the denafrips dacs (venus and up) do add a sense of midbass weight to the sound while still maintaining a nice sweet upper range
i tried the bricasti m1 se and to me it sound pretty much identical to the Weiss 501 (pre 4ch upgrade) they are in the clear and crisp school of sound... I have not heard the m21 maybe it is better/different
i do think the msb dacs are excellent (but $$), same imaging and clarity as the best like the dave and others but a touch more relaxed and dimensional, i’ll never part with my analog dac/pb
i had the am tubador and did not care for it, it sounded slightly veiled and low energy to me
good luck on your pursuit
