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.
