Hey Pal.
I have been looking at DACs too, I guess right now, looking seriously at the Musical Paradise, though I find the Gustard x30 compelling also, especially having really been enjoying my Gustard X20pro after mods for quite a few years. I don't know if the Musical Paradise can do both outputs or not. Looking around for information I found this Musical Paradise thread. In it there are some videos from Loic at Hifi Cave, for what its worth, one of them mostly comparing the Gustard R26 (resister ladder) to a Pontis and Venus, with a tease reference to his tuned up Musical Paradise at the end.
https://www.stereonet.com/forums/topic/612687-musical-paradise-mp-dx-dac/Over the last few years I have almost bought an R26 many times, and they do come up used. I just never dove in because I have for the most part loved the Gustard I have, to me quite a bit faster and more resolving in musical ways than it was stock. Seems the Gustard R26 has gotten a lot of praise from reviewers in comparison to the Holo Spring and other less costly ladder DACs, my interest the same reason as yours... wanting to actually hear a decent ladder DAC in my setup that is a good quality for the money, while being pretty fast and clear. But I have not heard it, so.....
