Take a look at the Matrix Audio Element X. I’d put mine up against a Lumin T2 any day of the week…and it’s about $1k cheaper. I briefly had the Altair G1 and the Matrix easily betters it. Also, the Matrix has the most advanced DAC chipset (ES9038PRO vs ES9028PRO & ES9038Q2M) of the three, and, unlike the Lumin, a built-in Noratel linear PSU.
