I used them both with a Red Wine Audio Isabellina and a NuPrime DAC-9, both of which are on the warm side. I do use an upgraded power supply (HDPlex), and to be honest I heard less of an improvement than I expected, both when using the Aries as DAC and streamer only. Others have had different experiences - I'd recommend checking out the Computer Audiophile forums for more detail.
I wouldn't say I love Lightning DS, as it's still a little buggy for me, but I've found it to be the most user-friendly app aside from Roon.
