Not heard the Dave, but I read a lot of reviews and ended up getting the Holo May KTE. It’s the most perfect sounding dac I’ve heard, and if you look at what others saying, who heard both, it beats the Dave. For the price of the Dave you can get more value and more sound elsewhere, because you’re paying top dollar for British employees doing research and development.
also don’t forget the technology in Dave is from 2014, as good as that was at the time, there’s some new developments that surfaced in the past years which could make the Dave obsolete. Besides I personally hate the design and the looks of the Dave:)
Regarding M-Scaler which is a must if you want to get the best out of Dave, it’s easily bested by hqplayer, but does require more effort than plug and play.
enjoy the music!
