I had both units and Benzman is correct on several things. I had the Lumin T2 first and sold it and bought the Cary DMS600. Since I was listening to tube amplifiers and a tube preamp, the Cary matched up well with the setup. The AKM sound smoother with slightly fuller bass while the Sabre sound brighter with maybe a bit more detail. The AKM can process the digital sampling rate from 44.1 kHz to 768 kHz while the Sabre dac processes 44.1–384 kHz. The Cary has much more flexibility plus you can use your CD Player as a transport and connect into the Cary to take advantage of the DAC’s built into the unit. It all depends on what sound you’re looking for. Both units are upgradable with their firmware. The Lumin software posed a bit of a problem but there IT was pretty good. I haven’t had any issues with the Cary thus far. It has been excellent. Both pieces are well built. For me, I love that I can use a phone (Android or an iPhone), a computer, or a tablet to control the Cary. What you saw on the screen of the Cary unit is what you saw on the hand device. Also connecting to a Roon Nucleus was very easy and convenient especially for ripping. I hope that helps.
