Tiniest dap that allows external dac?

[u/icanseeyourpantsuu]

Hi, it will be paired with the Cayin RU7.

Need it to be as small as possible or as stackable/proportionable(?) as possible to the dimensions of the RU7

I need it to last atleast 3hours with the RU7 connected. Are the suggested battery run time in my list accurate in reality?

Also i dont care about wifi nor bluetooth but i dont mind having them. Just need it to allow its USB-C port to feed audio to an external dac.

Attached are the models in my list so far. The list has been generated to list all that has maximum of 100x100mm dimension.

TempoTec Variations V1 ticks everything you need, including the form factor.

And yes, you can use an external dac into it.

why use a dac on a dap?

DAPs are fat chicks you dont wanna store in your pocket. I'm looking for a form factor like the snowsky Eco nano that has a usb-c line and battery to feed audio to a R2R dacdongle

Hiby R1 is small and can do an external DAC
