Source audio is from USB, playing Tidal Hi-Fi/Master tracks. Stuck between the Topping D30, Modi 3, and Khadas toneboard. I did read read the reviews by @amirm but I don't feel I was smart enough to really compare cause I wasn't able to really come to a conclusion ;') (lots of graphs and what not, but didnt know what meant what or which to compare apart from the SINAD graph). This DAC will be for a desktop setup with two monitor audio radius 45 bookshelf speakers that I may replace down the road, and a custom made sub (friend made it for me, subwoofer nerd, said it was a few hundred bucks in parts but gave it to me for free cause has so many sitting around, no idea what the specs are). Haven't settled on an amp yet, but will likely get something like a topping D10, or similar (whatever I can find around the same price range that is better). I don't need or want extra bells or whistles, just good quality sound.
