I'm looking for a cheap DAP (a few hundred dollars) to use only as a digital source, so basically I want most of the money to go into the interface, features, and build quality and not audio (DAC and amp section). Reason being is I use a Fiio Q5 for my portable setup and have several desktop setups, probably only need the DAP to pair with my Q5. Reason for not buying one in the first place is I wasn't expecting to use one. I currently use my Pixel 2, but would like to use something with better battery life and storage. Requirements: - Roughly the same size or smaller than the Q5. - Would like to use USB between the two. Optical could work as well. - Support FLAC upto 24bit/192kHz. Don't care too much about DSD. - At least 8 hours of battery in normal operation. - 256GB or larger. - Not too fragile. - No real budget, but I wouldn't want to pay more than a few hundred for a DAP when not using the DAC and amp portion. Optional: - Android based is preferred - Work with streaming services which means it needs to be able to use WIFI networks. - Support audio over bluetooth - Chromecast (is there any unit that actually support chromecast? Never looked.) Other thoughts: - If i was tight on space and had to use only the DAP or my Q5 (with my phone) I would use the Q5. - Shouldn't matter what my headphones or type of music is as the Q5 does all the actual work. - Not too picky on the interface as long as its not cumbersome to go through large amounts of files. - Hard to predict but it would suck if the manufacture just drops support (SW updates) soon after purchasing. - To be honest, I don't know if the DAP thing will work in my setup lifestyle wise. Its like anything else in the headphone/audio world, its a hobby and I'm curious. Anybody who says its not a hobby after getting many pairs of headphones and equipment is lying to themselves.
