As mentioned above, I've ripped all my CDs and put them on shuffle..just over 100 hours of material. I just received a Holo May DAC and wow..what an upgrade from my McIntosh MA12000 DAC. The ripped CDs sound so musical. Everything about the presentation is better. I'm streaming off iFi Zen Stream/ Roon Core i7 NUC/64TB Synology DS1522+ with dual SSD Cache.
