Upgrade from an Audio Alchemy DDP 1 + PS 5 power supply?

Have had this DAC for a couple years now with no complaints on sound quality but would like to (perhaps) try something new.  I have no preamp (except the  Audio Alchemy DDP-1) so want a DAC with remote volume control.  I was considering the LKS  MH DA004 when I bought the AA DDP-1 and the new Gustard X26 Pro sounds quite interesting.  My budget will max out around $1500 and I don't mind buying used.  Qualities should include high resolution and a very well defined soundstage.  Something on the brighter side will probably not work well in my system but spot-on neutral is desirable, possibly with a hint of warmth.  Options will be appreciated but, if you could make direct comparisons to the AA DDP-1 vs suggested DAC's, that would be great.  Thank you.
