interesting thought. I have an Aesthetix Romulus eclipse. With tubes, I get a sound that’s pleasing to my ears, lush like vinyl with digital detail. In hindsight I might have gone with a good transport e. g a vintage Esoteric and a separate DAC in order to upgrade as digital technology improves (assuming it does). So at least I’m not replacing a solid transport in addition to the DAC section. To me, the thing CDs bring is convenience over vinyl. If I’m listening to digital, its 50/50 CDs vs streaming tidal.
