DCS Bartok vs Lumin X1
 

Currently I compare Bartok with X1. For me it is very difficult to find differences. X1 has not completely run in. For now I would say the Bartok might be a very slight piece more dynamic/detailed. I do hear such differences only with selected parts of selected songs. Differences are so small. With high resolution music the differences might be more pronounced (I have only red book music)

With regard to prices, I guess there is hardly any cheaper solution available (including cables) that poses same sound quality.
