In January 2021, I was fortunate to review Nagra's Tube DAC and Classic PSU power supply. In my review, I said that the owners of this vacuum tube Hi-Res Audio DAC will be able to appreciate the "sonic glory" of this "high-performance component." So, I was not surprised that the Nagra Tube DAC and its PSU power supply were awarded Enjoy The Music.com's Best Of 2021 Award. After I finished the review, I was not psyched to return the $40,900 package consisting of the Nagra Tube DAC, Classic PSU power supply, and VFS Classic base to the distributor. I was captivated by the sound quality this digital front end contributed to my system. My reference DAC, an EMM Labs DA2, is no slouch, but this Nagra Tube DAC package costs twice as much.
