Well in pro audio I've heard all kinds of stuff, most impressed with the Apogee line. I got roped in to Chord by hearing the Hugo2 and loving it, realizing I could bring it on my trips. I liked it so much it got me listening in detail to the high-end stuff. Now I wish I hadn't lol. But Stereophile says some Meridian is as good as a Dave because it does MQA and sounds better on certain instruments. So I guess there are other alternatives out there.
