Lumin X1 or dCS Bartok


Both of these beasts look like they could be that “forever purchase”. These are basically the newest offerings from both well respected companies and are within spitting distance of each other price wise  (without the Bartok headphone option installed). Anybody heard both and able to comment?

I carry Lumin and have the X1 here, and was just at a client's place last week who has a dCS Vivaldi stack. I'd say the sound character goals of Lumin and dCS are probably best considered as different, so you'd need to hear them to decide which direction best matches what you're looking for.
@david_ten well, Lumin is using output transformers as part of their analog stage which adds some color but otherwise retains the detail provided by the ESS DAC chips.

To a large degree the goal and result is similar to that of the DAC I designed, which also uses output transformers combined with PCM1794A DAC chips.

dCS is not aiming for the same thing with their products, although with multiple filter settings you can influence the sound.
Listening to the Rossini right now, which has similar character to the Bartok. I came from a Mytek Manhattan II which is based on the ESS Pro. All I can say is it’s not even close between those two. The dCS has this smooth, natural presentation with incredible detail and separation. I loved the sound of the Mytek but it always had this hint of brittleness that I believe the dCS ring DAC and upsampling provide. 
@mayoradamwest I think you meant to say the dCS approach does not have the hint of brittleness that you heard with the Mytek?
