Headphoneus Supremus
I have the latest Questyle QP1R with the improved click wheel. I got it from Moon Audio. Absolutely no hiss.
Same model, no hiss with Etymotic ER4PTs. After several months with this DAP, the grumbles about the user interface fade against its superb sound quality and power, pocketable size, battery life, and storage capacity with 2 x 200GB microSD cards. Some people want the latest "features" (wifi, Bluetooth, streaming, MQA, Android with games and different music players, whatever), but for simple on-to-go high-quality listening from a library you own, this is it. For instance, I'd not get one of the high-end Sony or A&K units, they are just too bulky (and more expensive).
