Denon AH-D7200 Desktop stationary Dac/Amp suggested for classical and jazz

[pororom]

I need a Stationary Amp/Dac that I will use with the Denon AH-D7200 for listen classical music and jazz and I have 2 candidates:
Grace Design m900
RME ADI-2 DAC
The two incorporate the AKM 4490 chip.
I am interested in a warm sound to spend many hours without fatigue but at the same time be dynamic and with character.
What do you advise me and why?
Thanks in advance

Haven't tried the ones you posted, otherwise I'd go with an AudioGD NFB-11 or R2R-11. Or any Violectric and then order the DAC board installed.

I think I need the one with a low output impedance since Denon are very sensitive.
I'm still searching the forums and I can not find any recommendation that has been verified.
I am looking for a that is not a battery, stationary, with a DAC 32/384, asynchronous USB and measured max (20cm x 20cm).
Does not what I'm looking for exist?
Maybe the combination of a pure DAC and a headphone amplifier with low output impedance would be a better solution?
