I use my n5 as my mp3 player in my car but the sound sucks. I'm thinking of getting a dac to fix this.

I have a otg cable to plug in my usb key that contains my mp3 library. So first I know i will need a y otg, have some all ready but not sur I have the right one but that is a detail. I dont really care about simultaneously charging my phone.

So what good dac do you suggest. Keep in mind I don't have a lot of money, not to sure what kind of budget yet.

Thanks
