Bottom Line

This review addressed two issues: 1) how the exaSound e20 sounds, and 2) how DSD music files sound. For me, listening to DSD files was a new experience, which the e20 made possible. And what an experience it was! Based on the limited number of DSD files I had available, DSD files are quite spectacular. I know lots of readers find it amusing when reviewers rave about new equipment, but for me DSD files made all the PCM files I’ve heard, even the highest-resolution PCM files, sound, well, digital. In a world where the highest accolade for digital gear is how much it sounds like analog, DSD files are off the scale. I’m going to have to think long and hard about whether I’ll ever download another high-resolution PCM file. A listening buddy and hi- fi dealer who has so far been a staunch analog holdout was so thoroughly impressed that he went away planning to implement DSD playback in his store. It’s too early to tell if DSD files will become widely available, but I hope so. Pricing them at the same level as 192/24 files might greatly speed up their acceptance.

For me, the exaSound e20 was a game-changer. It played standard PCM files extremely capably, but its greatest strength was its ability to play DSD files in their native format, which took my system to a new and higher level. The e20 is an attractive, compact, and clearly thoughtfully-designed example of a modern DAC. It produced a rich detailed sonic picture, with solid bass and extended high frequencies. I heartily recommend that if you’re in the market for a new DAC, you consider one with DSD-playback capability, like the exaSound e20.
