I'm haven't completely settled yet ... as @mahler123 says, i'm worried about the age of the device, although many reports says that it is still among the best.
So i keep going back and forth with buying a cheaper streamer such as an Eversolo DMP-A6 that gets great reviews (and given it's price, i could change it every 2-3 years), and add a 5K dac to it (T+A DAC 200, Soulnote D2, Danafrips Terminator ...) ... or get the X1 and enjoy it for as long as possible.
I was looking at reviews of the previous TOTL from Lumin (the S1) and even when the X1 was released, reviewers were saying that the S1 was still a good device.
Now ... i('m not sure it helps with your problem ... it doesn't really helps me decide :-)
