Hifiberry Digi 2 Pro
Ordered a second Digi 2 Pro unit. The first was faulty and I returned it. The second unit worked right out of the box no editing of config.txt was required at all. Amazing sound via coax. Hifiberry OS recognition of Digi 2 Pro and a DSP module happened with no technical issues. My setup: Pi 4 8Gb + Digi 2 Pro + DSP module via Blue Jeans Coax cable to Dacmagic 200M to RCA ton Sony STR DH790 receiver. PS. To my ear DAC 2 HD (which I own as well) still sounds a little better (not so digitally ) but it could be just a placebo effect…. I wish I could upload photos for setup… here.
